African clawed frog embryos
Grant N. Wheeler (UEA)
The Wheeler lab in the School of Biological Sciences at UEA on the Norwich Research Park carries out chemical screens to identify compounds that affect pigment cell pattern in African clawed frogs (Xenopus laevis). This is useful to answer questions in developmental biology plus pigment cells in humans can give rise to melanoma cancer. Identified compounds that affect pigment cell growth could also be used against melanoma cells. The image shows Xenopus embryos at the 2 and 4 cell stage of development 2 hours after fertilisation.
