Histone lysine lactylation is the newly identified histone PTM that utilizes the lactyl moiety for its modification. Although histone lysine lactylation is considered an essential outcome of the Wardburg effects and the interconnection between cellular metabolism and gene regulation, the developmental contexts involving this PTM are largely unknown. In this study, we comprehensively observed histone lysine lactylation during Drosophila oogenesis, one of the developmental contexts in which chromatin regulation plays crucial roles.Results: Our study revealed that lactylation on the specific histone lysine mainly occurs in the oocyte karyosome and condensed meiotic chromosome, suggesting histone lysine lactylation has a vital role in female meiosis. Interestingly, one of the histone lysine lactylations, lactylation of lysine 14 of histone H3, is intensively observed in the meiotic germline in the mouse ovary, suggesting that lactylation has an evolutionarily conserved role.Conclusions: Our results revealed that histone lysine lactylation is predominantly present in transcriptionally repressive meiotic chromatin, which contradicts the previously reported function of histone lactylation in transcriptional activation. This study, therefore, provides the first fundamental information to understand the role of histone lysine lactylation in the germline and repressive chromatin.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143729298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Induction in 3 dpf larvae restricts hand2 lineage labeling to mesoderm-derived components of the branchial arches, heart, liver, and enteric neurons.Conclusions: hand2 progenitors from the lateral plate mesoderm and ectoderm contribute to numerous lineages in the developing embryo. At later stages, hand2-expressing cells are restricted to a subset of lineages in the larva.

For that study, we created a SHF-specific Sox9 knockout mouse. In addition to the presence of primary atrial septal defects in half of the offspring, we found that virtually all specimens also developed a ventricular septal defect. Histological analysis suggested that the ventricular septal defects resulted from developmental perturbation of the mesenchymal structures within the outflow tract. In the current study, we investigated the role of Sox9 in the SHF in the development of these tissues.Results: Sox9 is expressed in all mesenchymal cell populations in the developing outflow tract, including a cohort of endocardial-derived cells that originate from the SHF-derived endocardium. SHF-specific deletion of Sox9 inhibits the formation of this cell population and ultimately leads to truncation of the mesenchymal outlet septum. This prevents complete fusion of this outlet septum with the atrioventricular mesenchymal complex, resulting in ventricular septal defects.Conclusions: In combination with our first paper on the role of Sox9 in atrioventricular septation, data presented in this study demonstrate that Sox9 expression in the SHF is of critical importance for the proper formation of the septal structures in the developing heart.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143709003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regenerative biology is also a sub-discipline of developmental biology, studying how tissues and organs heal and regenerate after injury. One aspect of healing and regeneration is the behavioral recovery of the whole organism, involving the nervous system and coordinated movements in three-dimensional space. Behavioral recovery is often a secondary measure in many regeneration studies, primarily focusing on molecular and cellular mechanisms involved in structural recovery. Studies and frameworks in DPB, however, suggest that behaviors may have an active role in the regeneration process, and integrating regenerative biology with DPB would provide a basis for behavioral research on regenerative systems as a separate biological question to increase our understanding of behavioral recovery. Here, I introduce the probabilistic epigenesis framework from DPB and elaborate on how it reveals gaps in our knowledge concerning regeneration and behavioral recovery. I close with an initial regenerative history framework to guide regenerative biologists and bioengineers studying behavioral recovery to address these gaps and optimize behavioral recovery with regenerating tissue.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far, these factors remain to be detailed in the axolotl model. In this descriptive study, we have investigated metabolic changes that occurred during cardiac regeneration in the axolotl.Results: We describe systemic and local cardiac metabolic changes after injury involving an early upregulation of glucose uptake and nucleotide biosynthesis followed by a later increase in acetate uptake. We detect several promising factors and metabolites for future studies and show that, unlike other popular animal models capable of intrinsic regeneration, the axolotl maintains its cardiac regenerative ability under hyperoxic conditions.Conclusions: Axolotls undergo dynamic metabolic changes during the process of heart regeneration and display a robust reparative response to cardiac cryo-injury, which is unaffected by hyperoxia.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In adults, they normally remained in a quiescent state and activated upon stimulation to undergo self-renewal or myogenic differentiation. This process was complexly regulated by cytokines, and the molecular mechanisms that promoted MuSCs activation remained largely unknown.Results: Here, we analyzed transcriptome data from MuSCs activated by different stimuli using weighted gene co-expression network analysis (WGCNA) and identified the key long non-coding RNA SNHG1 (lncSNHG1), which promotes the transition from the quiescent to the activated state of MuSCs. Overexpression of lncSNHG1 was able to promote the proliferation and differentiation of MuSCs, whereas knockdown resulted in the opposite results. Mechanistically, the disruption of the Wnt/β-catenin pathway blocked the quiescence exit induced by lncSNHG1.Conclusions: We conclude that lncSNHG1 is a key factor that promotes the transition from the quiescent to the activated state of MuSCs and promotes cell proliferation and differentiation through the Wnt/β-catenin pathway.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143673423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This field, known as neuroplacentology, has greatly expanded possible etiologies of neurodevelopmental disorders by exploring the influence of placental function on brain development. It is also well-established that brain development is influenced by craniofacial morphogenesis. However, there is less focus on the impact of the placenta on craniofacial development. Recent research suggests the functional influence of placental nutrients and hormones on craniofacial skeletal growth, such as prolactin, growth hormone, insulin-like growth factor 1, vitamin D, sulfate, and calcium, impacting both craniofacial and brain development. Therefore, interactions between the placenta and both fetal neurodevelopment and craniofacial development likely influence the growth and morphology of the head as a whole. This review discusses the role of placental hormone production and nutrient delivery in the development of the fetal head-defined as craniofacial and brain tissue together-expanding on the more established focus on brain development to also include the skull (or cranium) and face.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143656302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non-lethal salinities. We hypothesized embryos at higher salinities will display epidermal plasticity as a coping response and increase energy expenditure related to osmoregulation demands, thereby reducing energy for growth and development.Results: Scanning electron microscopy revealed an extra mucus-secreting cell type and higher ionocyte proportions in the X. laevis epidermis, suggesting more osmoregulatory machinery than L. sylvaticus. Under elevated salinity, X. laevis displayed greater increases in goblet cell proportions, mucus secretion, and reductions in ionocyte apical area compared with L. sylvaticus. Although both species increased oxygen consumption rates and reduced body length with elevated salinity, these effects were proportionally greater in L. sylvaticus at the highest salinity, and only this species slowed developmental rates.Conclusion: These findings support the hypothesis that frog embryos respond to salinity by altering the cellular landscape of their epidermis. We show that epidermal cell types, as well as the magnitude of epidermal plasticity and energetic trade-offs in response to salinity, vary among amphibian species.","PeriodicalId":11247,"journal":{"name":"Developmental Dynamics","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143647400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
