A new role of hindbrain boundaries as pools of neural stem

Jul 08,2016·Compartment boundaries are an essential developmental mechanism throughout evolution,designated to act as organizing centers and to regulate and localize differently fated cells.The hindbrain serves as a fascinating example for this phenomenon as its early development is devoted to the formation of repetitive rhombomeres and their well-defined boundaries in all vertebrates.A novel role for Pax6 in the segmental organization of the Boundary cells regulate a switch in the expression of FGF3 in hindbrain Boundary cells regulate a switch in the expression of FGF3 in hindbrain rhombomeres.Expression study of cadherin7 and cadherin20 in the embryonic and adult rat Expression study of cadherin7 and cadherin20 in the embryonic and adult rat central nervous system

An Integrated Gene Regulatory Network Controls Stem Cell

Jun 12,2007·Fgf3 expression in the mesenchyme underlies the cervical loops and correlates with their size,and FGF3 cooperates with FGF10 as a mesenchymal signal that stimulates the proliferation of dental epithelial stem cells and transit amplifying (TA) cells.BMP4 represses Fgf3 expression,whereas Activin,which is preferentially expressed in labial An integrated gene regulatory network controls stem cell Mesenchymal FGF3 stimulates epithelial stem cell proliferation,and BMP4 represses Fgf3 expression.In turn,Activin,which is strongly expressed in labial mesenchyme,inhibits the repressive effect of BMP4 and restricts Fgf3 expression to labial dental mesenchyme,resulting in increased stem cell proliferation and a large,labial stem cell niche.
