Cell viability with biomembrane components. Analysis of bone marrow mesenchymal stromal cells (BMSC) (a) and human skin fibroblasts (hFB) (b) viability and capacity of cells to proliferate following the PL stimulation in the presence of SS. Cells were maintained up to 72 h in Serum-free medium (SFM), or SFM supplemented with PL (PL), Sericin (SS), PL and Sericin (PL:SS). Cell viability was determined by a Thiazolyl blue staining (MTT assay), **** p < 0.0001, *** p < 0.001, ** p < 0.01, * p < 0.05.
