Protection of bone marrow, mononuclear, and CD34+ cells by enclosing within the biochemical compound solution during...

We have chosen collagen, chitosan acetate, hyaluronic acid, and propolis as model biochemical compound solution to determine the influence of cell carrier mechanics on cell viability and functionality during and after transplantation. Suspending of bone marrow (BM), mononuclear (MN), and CD34+ cells into a biochemical compounds solution is an attractive tool to achieve to protect and ensure reproducible deliver. Hyperglycemic rats were randomly divided into 2 groups: to receive no cell treatment or approximately 1 × 10⁵ of BM, MN, and CD34+ cells within the PBS or biochemical compound solution. These cells were infused into the hyperglycemic rats on day 10 and again on day 20. At each time point, the animals were anaesthetized with ether, and 200 μL of blood was drawn from the tail vein. Samples were collected to determine whether BM, MN, and CD34+ cell affected glucose content and insulin production. Our results exhibit the use of biochemical compound solution method to overcome the cell transplantation problem during and after injection of these cells into rats. These findings are supported by resulting in significantly greater insulin production and more decreased glucose content than cells injected in PBS only (P < 0.05). These effects displayed the following hierarchy: hyaluronic acid > chitosan acetate > collagen > propolis solution. Our results showed that these compounds demonstrated a capacity to encapsulate the BM, MN, and CD34+ cells. It is proven by decreasing glucose content and increasing insulin secretion by pancreatic cells. The uniqueness of our study is the improvement of current transplantation efficiency.
