  • gene expression
  • In this study intended to elucidate the mechanism for the transition from crown morphogenesis to the initiation of root formation, we focus on the differential gene expression patterns of fibroblast growth factor (Fgf) 10 mRNA between continuously growing teeth and limited-growth teeth ( Fig. 1A ).

  • One signal, BMP4, has been shown to induce morphologic changes in dental mesenchyme and mesenchymal gene expression via Msx1, but BMP4 cannot substitute for all the inductive functions of the dental epithelium. (semanticscholar.org)
  • Meanwhile, Wnt inhibition acts later during gastrulation, and is essential for maintenance of organizer gene expression throughout gastrulation, a role which may depend on its ability to block the expression of a host of ventral, posterior, and lateral fate-specifying factors.

  • activity
  • Based on our current understanding of Myod, it is reasonable to suggest that the regulated activity of a single factor that broadly interacts with many cellular components might be a common mechanism for orchestrating a complex response to an initiating event. (biologists.org)
  • development
  • The cerebral spinal fluid (CSF) flow tract is a vital lifeline for supplying the brain with essential nutrients and growth factors throughout development and into adulthood. (physiology.org)
  • mouse
  • Although malformation of the SCO during gestation leads to ventricular dilation and aqueductal stenosis before birth (FIGURE 1, B AND C ⇓ ) ( 32 , 80 ), the involvement of specific factors has been slowly elucidated over the past decade through the analysis of mutant mouse models.
