Glossary Embryogenesis

process where a fertilized egg develops into an embryo

Embryogenesis, also known as embryonic development, is the process by which a fertilized egg (zygote) develops into a fully formed embryo. This complex process involves cell division, differentiation, and morphogenesis, where cells specialize and organize into tissues and organs. It is a critical phase in prenatal development, laying the foundation for all the body's structures and systems.

research Transdifferentiation of corneal epithelium: evidence for a linkage between the segregation of epidermal stem cells and the induction of hair follicles during embryogenesis.

55 citations , January 2004 in “The International Journal of Developmental Biology”

This study reports that corneal transient amplifying cells can be reprogrammed into epidermal cells capable of forming hair follicles in response to embryonic dermis signals.

research Survival of patchwork melanoblasts is dependent upon their number in the hair follicle at the end of embryogenesis

29 citations , June 1998 in “Developmental Biology”

This study found that the patchwork mutation in mice affects melanocyte survival in hair follicles, leading to a variegated coat pattern without partially pigmented hairs due to a community effect among melanoblasts.

research CD10 and CD34 in fetal and adult human hair follicles: dynamic changes in their immunohistochemical expression during embryogenesis and hair cycling

25 citations , July 2008 in “British Journal of Dermatology”

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

research Temporal expression and steroidal regulation of piRNA pathway genes (mael, piwi, vasa) during Silurana (Xenopus) tropicalis embryogenesis and early larval development

23 citations , April 2010 in “Comparative Biochemistry and Physiology Part C Toxicology & Pharmacology”

This study found that exposure to sex steroid biosynthesis inhibitors increases the expression of piRNA pathway genes in frog larvae, suggesting these genes play a role in gonadal sex differentiation.

research Epidermal Deletion of Rac1 Causes Stem Cell Depletion, Irrespective of whether Deletion Occurs during Embryogenesis or Adulthood

18 citations , February 2007 in “Journal of Investigative Dermatology”
