Article: Researchers from Washington University report details of new studies and findings in the area of cell proliferation.(Report)

"Bone morphogenetic protein (BMP) signaling is essential for the induction and subsequent development of the lens. The purpose of this study was to analyze the function(s) of the type 1 BMP receptor, Acvr1, in lens development," investigators in the United States report (see also Cell Proliferation).

"Acvr1 was deleted from the surface ectoderm of mouse embryos on embryonic day 9 using the Cre-loxP method. Cell proliferation, cell cycle exit, and apoptosis were measured in tissue sections by immunohistochemistry, immunofluorescence, and TUNEL staining. Lenses formed in the absence of Acvr1. However, Acvr1(CKO) (conditional knockout) lenses were small. Acvr1 ...
