Poly-L-lysine solution

Poly-L-Lysine Solution has been used to co at culture dishes to culture U2-OS cells and primary cortical neurons.

Poly-L-lysine serves as a coating substance to ensure better attachment of cells to culture surfaces. Research shows th at plates coated with poly-L-lysine (PLL) demonstrated an accelerated cell growth rate. Culturing mesenchymal stem cells (MSCs) on PLL-coated substrates has been found to safeguard the stemness properties of these cells and inhibit senescence. PLL-coated plates have demonstrated enhanced MSC growth and up-regulated the expression of genes associated with cell adhesion, differentiation, proliferation, and signaling. Moreover, porous PLL-coated surfaces have shown improvements in cell proliferation and the osteogenic differentiation of MSCs.
