Retinal Progenitor Cells Exhibit Cadherin-Dependent Chemotaxis across Transplantable Extracellular Matrix of In Vitro Developmental and Adult Models

Figure 4

Measurement of the chemotaxis of stem-like cells. (a) Numbers of motile Drosophila progenitors (DPs) exposed to concentration gradients of insulin (N = 12), brain-derived neurotrophic factor (BDNF, N = 12), and pyramus (Pyr, N = 12) normalized to control (media only, N = 12). (b) Numbers of motile Mus progenitors (MPs) in response to concentration gradients of insulin-like growth factor 1 (IGF-1, N = 30), epidermal growth factor (EGF, N = 27), and stromal cell-derived factor 1-alpha (SDF-1α, N = 28) and normalized to control (media only, N = 30). Bars indicate statistically significant increases compared to control ().
