In essence, each cell fate in the human body is a unique but stable output state of the genome, maintained by positive and negative feedbacks from both inside and outside the cell (a stable cell state). Traditionally, defining a cell fate means identifying a unique combination of transcriptional factors expressed by the specific cell type. The hundreds of transcriptional factors in the genome, however, have complicated the task of simplifying cell fate representation and obtaining insights into its regulation. Moreover, results from this approach provides only a mostly static picture, with each cell fate/state disconnected from one another. An alternative approach instead defines cell fates by determining their relationship to each other, through identifying the signaling pathways that control each step of their lineage transition from a common progenitor during development. Decades of studies have shown only a handful of signaling pathways are sufficient to specify all cell fates in the body, simplifying the execution of such a strategy. In this review, I will argue this alternative approach is not only feasible but also has the potential of simplifying the cell fate landscape as well as facilitating the engineering of different cell fates for regenerative medicine.</p>","PeriodicalId":75257,"journal":{"name":"Trends in developmental biology","volume":"15 ","pages":"53-62"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10312135/pdf/nihms-1910961.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9806924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, therapeutic use of the Type 2 diabetes drug metformin has expanded to the treatment of pre-diabetes, polycystic ovarian syndrome, and gestational diabetes. Because metformin both undergoes renal excretion and binds to receptors on the placenta, the fetus receives equivalent maternal dosing. Although no teratogenic nor short-term harmful fetal impact of metformin is known to occur, the effects of metformin exposure on longer-range offspring development have not yet been fully elucidated. This review encapsulates the (albeit limited) existing knowledge regarding the potential longer-term impact of intrauterine metformin exposure on the development of key organs including the liver, central nervous system, heart, gut, and endocrine pancreas in animal models and humans. We discuss molecular and cellular mechanisms that would be altered in response to treatment and describe the potential consequences of these developmental changes on postnatal health.

While many have assessed the factors influencing gestation length in humans, and there has been considerable interest in the pregnancy duration of domesticated farm animals, this topic has not been re-assessed recently in rhesus monkeys, the most commonly used primate in biomedical research. In older articles, it's gestation length was typically reported to be 165 days, although most authors acknowledged that viable pregnancies could occur out to 180 days. Predicting the normal range of acceptable due dates has important veterinary implications for when to intervene in a prolonged pregnancy. Using archival records from a large, established breeding program, gestation lengths and infant birthweights were analyzed for 408 pregnancies across a 25-year period. The potential influence of maternal factors, including age and parity, was assessed. Familial concordance in gestation length within mother-daughter matrilines was examined, as well as similarity in length across repeat pregnancies for 84 multiparous females. Mean duration from mating to delivery was 168.8 days, longer than reported in most but not all previous articles. Many females birthed successfully at a longer duration that might have prompted consideration of a caesarian delivery. Gestation length for an individual female was fairly stable and significantly correlated across multiple pregnancies. There was not a pronounced transgenerational influence on gestation length even though familial propensities for birthing small and large infants were evident in the female descendants. Typical pregnancy lengths and birthweights are provided as reference norms to assist other breeding programs and to enhance our understanding of the natural reproduction of rhesus macaques that still live in many forested and urban locations across South Asia.</p>","PeriodicalId":75257,"journal":{"name":"Trends in developmental biology","volume":"14 1","pages":"63-72"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9012481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43949998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mouse and human ZP is composed of three or four unique proteins, respectively, called ZP1-4, that are synthesized, processed, and secreted by oocytes during their growth phase. All ZP proteins have a zona pellucida domain (ZPD) that consists of ≈270 amino acids and has 8 conserved Cys residues present as four intramolecular disulfides. Secreted ZP proteins assemble into long fibrils around growing oocytes with ZP2-ZP3 dimers located periodically along the fibrils. The fibrils are cross-linked by ZP1 to form a thick, transparent ECM to which sperm must first bind and then penetrate during fertilization of eggs. Inactivation of mouse <i>ZP1, ZP2,</i> or <i>ZP3</i> by gene targeting affects both ZP formation around oocytes and fertility. Female mice with eggs that lack a ZP due to inactivation of either <i>ZP2</i> or <i>ZP3</i> are completely infertile, whereas inactivation of <i>ZP1</i> results in construction of an abnormal ZP and reduced fertility. Results of a large number of studies of infertile female patients strongly suggest that gene sequence variations (GSV) in human <i>ZP1, ZP2,</i> or <i>ZP3</i> due to point, missense, or frameshift mutations have similar deleterious effects on ZP formation and female fertility.

Previous research has documented that there are also many physiological and health consequences of being born either small-for-gestational age (SGA) or large-for-gestational age (LGA). Analyses of breeding animals have demonstrated further that a gravid female exerts a strong influence on the size of her infant by term, and this permissiveness or constraint over fetal growth can be transmitted from mothers to their daughters. The following research tested additional hypotheses about matrilineal effects on BW by examining records from a large breeding colony of rhesus monkeys across multiple generations. The analyses utilized BW of 1710 infant monkeys obtained over 4 decades. In addition to determining the association between the birth weight (BW) of a female and her own infants birthed later as a mother, the multi-generational transmission of birth size from a grandmother through her daughters to the next generation was examined. Other maternal influences were evident, including a progressive increase in infant BW with parity, which synergized with matrilineal effects across a female's reproductive life. In addition, our modeling indicated that if an infant's BW was discordant-a SGA female birthing a larger daughter-the discrepant fetal growth pattern could be accentuated in the next generation.
