A significant model for the timing of ductal formation in culture (P = 0.005) involved only donor ancestry and height. Potency of the stem cell specifies the differentiation potential i.e., the potential to differentiate into different cell types. Dependent on stem cell potency, their progeny gives rise to various differentiated cells either directly, or indirectly via transient amplifying cells. Patrick Seale: Our lab investigates the transcriptional pathways that control the development, differentiation and function of adipose cells in normal development and in obesity. Discrete regulation of β-catenin-mediated transcription governs identity of intestinal epithelial stem cells The gut is an important organ, in charge of absorbing water and nutrients from the food and drinks we ingest. Autologous LESC (limbal epithelial stem cells) expanded on a cellular matrix to: - Maintain stem cells undifferentiated - Form an epithelial cell sheet for transplantation - Based on Pellegrini et al., Stem Cells (2014) 19 Potency & … Although this difference has, in the past, been largely attributed to socioeconomic factors, increasing data suggests that there are intrinsic differences in African American breast tissue compared with European whites. This histone changes as embryonic stem cells turn into somatic cells. Nancy Speck: Hematopoietic stem cells … As most clinical applications do not require the creation of an embryo, pluripotency is the most desired level of potency in stem cells for it has the widest array of application. Substantial evidence supports the idea that stem cells in the interfollicular epidermis are less potent than bulge stem cells, leading to speculation that they are progeny, perhaps unipotent progeny, of multi… A simple, reproducible, animal-material free method for cultivating and characterizing cornea limbal epithelial stem cells (LESCs) on human lens capsule (LC) was developed for future clinical … Autologous LESC (limbal epithelial stem cells) expanded on a cellular matrix to: - Maintain stem cells undifferentiated - Form an epithelial cell sheet for transplantation - Based on Pellegrini et al., Stem Cells (2014) 19 Potency & … Hair follicle (HF) development and growth are dependent on epithelial-mesenchymal interactions (EMIs).
