This tightly regulated cascade of events enables the differentiation of a germline stem cell into a mature oocyte. Autophagy contributes to cellular quality control, nutrient sensing, and the regulation of developmental cell death, all of which are critical for proper egg development and maturation. Disruption of autophagy influences oogenesis, resulting in defective egg chamber development, altered apoptotic dynamics, abnormally shaped mitochondria and compromised mitophagy. Methodological advances, including immunofluorescence-based detection, live imaging using fluorescent reporters, and ultrastructural analysis via transmission electron microscopy, have significantly enhanced the ability to monitor autophagic activity in the ovary. This review summarizes current evidence that establishes autophagy as a key regulatory mechanism during oogenesis.

These mechanisms typically involve complex interactions between signaling pathways, which can be further influenced by mechanical forces as the embryo grows. Here, we investigate the patterning of the ring of conjunctival placodes in the anterior eye of chicken embryos by functionally manipulating the BMP signaling pathway. Specifically, we electroporated a <em>TWSG1</em> plasmid at HH27 to modulate BMP signaling during the pre-patterning phase and examined the effects on placode formation and key developmental pathways. Our results show that modulation of BMP signaling at HH27 influences placode development, morphology and spacing three days later, at HH34. qPCR data confirm an initial and statistically significant upregulation of <em>FGF20</em> and <em>WNT2B</em> 6 h after electroporation. However, one day later (at HH29), only <em>β-catenin</em> is significantly elevated. Multiplex fluorescent <em>in situ</em> hybridization shows <em>WNT2</em> expression in the conjunctival placodes and papillae for the first time. This <em>WNT2</em> expression is colocalized with <em>β-catenin</em> in controls and remains spatially colocalized after electroporation. Together, these results provide functional evidence that BMP signaling regulates both canonical WNT/β-catenin and FGF pathways during early placode formation and support a model in which BMP may act as the inhibitor in a Turing-like reaction–diffusion mechanism underlying conjunctival placode patterning in the anterior eye.</div></div>","PeriodicalId":11070,"journal":{"name":"Developmental biology","volume":"532 ","pages":"Pages 115-124"},"PeriodicalIF":2.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145997426","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}

Examples of both are found in timeseries for traits ranging from growth to division timing during development to duration of life history stages. We offer practical recommendations, including the use of a previously proposed simple statistical test, for detecting correlations and, no less importantly, the absence of correlations in the kinds of timeseries that are often generated by developmental biologists. We pay particular attention to discriminating between real, biologically meaningful correlations and the artifactual ones that often arise when data are collected in multiple batches.
