> It’s the stuff that holds the membranes of our bodies together
laminin is part of the matrix but it isn't the part that holds cells together
laminin is what gives cells their purpose. Heart cells are what they are because of the type of laminin in the cardiac matrix
cardiac stem cells can survive in a petri dish but without matrix and cardiac laminin they aren't any specific cell type
perhaps anons member, a few years ago, the first successful transplant of "lab grown" lungs into a pig using the pig's own stem cells, without need for immunosuppressants, etc. The stem cells weren't the key. The stem cell hype is just an easy grift. Stem cell transplants don't regenerate damaged tissue. The best stem cells are already there, taking care of the tissue as they have been doing since conception. There is a reason they aren't already regenerating the damaged tissue - damaged extracellular matrix. Tissue maintenance and regeneration is in the matrix, laminins.
