"Adipose tissue extracellular matrix: newly organized by adipocytes during differentiation”
The data from this study suggests that in vivo under conditions permissive for adipose conversion, the production and organization of ECM, accompanied by hyperplasia and hypertrophy of precursor cells, gives rise to adipose tissue in skeletal muscle with its own ECM products. These data further suggest that each ECM protein might have some role for the adipocytes in forming tissue.
