Understanding cell and tissue size and shape regulation in a stem
... computational morphodynamics approach Plant meristems are stem cell niches continuously providing new cells throughout the life of a growing plant. The maintenance of the shoot apical meristem is regulated by an interaction between hormones and a gene regulatory network. A negative feedback between ...

β1 Integrin Participates in Endoglin-Dependent Inhibition of Prostate
... Our current objective is to analyze the signaling pathways downstream of endoglin that lead to the inhibition of prostate cancer cell migration and invasion. We have observed that endoglin expression has a dramatic effect in the organization of the actin cytoskeleton in PC3-M cells. Interestingly, e ...
