On a larger scale, tissue culture helps supply the market with new subspecies and varieties. Tissue culture is particularly useful for growing challenging plants such as specific orchid breeds. Web16 Jun 2003 · The tip cells respond to VEGF-A only by guided migration; the proliferative response to VEGF-A occurs in the sprout stalks. These two cellular responses are both mediated by agonistic activity of VEGF-A on VEGF receptor 2. Whereas tip cell migration depends on a gradient of VEGF-A, proliferation is regulated by its concentration.
