Japan's Dongda team has developed a new method for large-scale cultivation of hematopoietic stem cells

It is believed that this method can also be used in human cells, and it is expected to be a new way to provide the required transplanted cells in the treatment of leukemia and other blood diseases"As long as there are a small number of hematopoietic stem cells, they may be able to increase their number and transplant to multiple patients," Yamasaki said < br / > this study found that although the protein "albumin" contained in bovine serum is often used in cell culture, in fact, the impurities mixed in the extraction process will make hematopoietic stem cells differentiate into other cells< br / > using polyvinyl alcohol resin instead of protein can prolong the culture time from about one week to several months, and can proliferate up to 900 times per monthBy transplanting the mice, the team confirmed that they also had the function of producing blood cells< br / > hematopoietic stem cell transplantation (HSCT) is one of the methods to treat leukemia and other diseases that can not generate blood cells normally, but there are always problems such as insufficient cell providers and insufficient proliferation of high-quality cells.
