The present study suggests that the membrane-binding molecules of mesodermal cells and/or the modulated extracellular matrix (ECM) with them play an important role in induction of the central nervous system. Artificially mesodermalized ectoderm (mE) or chordamesoderm (cM) was placed on a collagen an

β¦ Synopsis
Neural plates which are induced in the dorsal ectoderm of Triturus by the underlying mesoderm acquire, in turn, neural-inducing activity. This process is correlated with the appearance of neural-inducing activity in the microsomal fraction of the neural plate homogenate. The high-speed supernatant also acquires inducing activity after neural induction, but to a lesser extent. The experiments suggest that a masked neuralizing factor, which is already present in the ectoderm, is in part activated and exported from the inducing neural plate cells.
