H-Ile-Lys-Val-Ala-Val-OH is one of the most potent active sites of laminin-1. H-Ile-Lys-Val-Ala-Val-OH promotes cell adhesion, neurite outgrowth, and tumor growth. H-Ile-Lys-Val-Ala-Val-OH stimulates BMMSC population growth and proliferation by activating MAPK/ERK1/2 and PI3K/Akt signalling pathways In Vitro H-Ile-Lys-Val-Ala-Val-OH (0-2.5 mM, 0-48 h) induces proliferation and proliferating cell nuclear antigen (PCNA) synthesis of bone marrow mesenchymal stem cell (BMMSC). H-Ile-Lys-Val-Ala-Val-OH (5 mM, 24 h) induces the BMMSC cell cycle for cells to enter S phase from G0/G1 and arrests them from entering G2/M phase. H-Ile-Lys-Val-Ala-Val-OH (0-2.5 mM, 0-48 h) activats MAPK/ERK and PI3K/Akt signalling pathways by enhancing phosphorylation levels of ERK1/2 and Akt in the BMMSCs. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Proliferation AssayCell Line: BMMSC Concentration: 0, 0.004, 0.02, 0.1, 0.5 and 2.5 mM Incubation Time: 0, 12, 24, 36, 48 h Result: Stimulated proliferating cell nuclear antigen (PCNA) synthesis and induced proliferation of bone marrow mesenchymal stem cell (BMMSC) in a dose- and time-dependent manner. Cell Cycle AnalysisCell Line: BMMSC Concentration: 5 mM Incubation Time: 24 h Result: Induced the BMMSC cell cycle for cells to enter S phase from G0/G1 and arrested them from entering G2/M phase; the increased proportion of S phase in cell cycle was considered to be a sign of BMMSC proliferation. Western Blot AnalysisCell Line: BMMSC Concentration: 0, 0.004, 0.02, 0.1, 0.5 and 2.5 mM Incubation Time: 0, 12, 24, 36, 48 h Result: Increased significantly the levels of p-ERK1/2 and p-Akt in a dose- and time-dependent manner.
