		Disengagement from extracellular matrix (ECM) is known to prejudice islet cell survival, notably by inducing apoptosis and necrosis (4).
		To determine whether the 804G matrix is able to serve as a survival ligand for primary rat pancreatic [beta]- cells, TUNEL and ELISA were performed on cells cultured on 804G matrix or on pLL (a nonspecific adhesive polymer)-coated Petri dishes.
		Given that the 804G matrix stimulates the ERK cascade and that this signaling pathway is involved in the pro-survival effects of this matrix, we hypothesized that this cascade might mediate the effect of the matrix on I[kappa]B[alpha] gene expression.

		Microcarriers containing extracellular matrix material from mutant embryos likewise did not stimulate neural crest cell migration in either mutant or wild-type embryos (Figure 2C, D).
		The microcarriers containing wild-type extracellular matrix, however, were able to stimulate neural crest migration from both the mutant and wild-type crests (Figure 2E, F), demonstrating the importance of the extracellular matrix in neural crest cell migration.

		The tumour extracellular matrix acts as a barrier to the delivery of therapeutic agents.
		To test the hypothesis that extracellular matrix composition governs the penetration rate of macromolecules in tumour tissue, we measured the diffusion coefficient of nonspecific IgG in three rhabdomyosarcoma subclones growing as multicellular spheroids in vitro or as subcutaneous tumours in dorsal windows in vivo.
		Penetration of therapeutic macromolecules through tumour extracellular matrix might thus be largely determined by the host organ.
