| description | The invention discloses a preparation method of umbilical cord mesenchymal stem cells. The preparation method comprises the following steps of: cutting Wharton's jelly into tissue blocks with the size of not more than 2mm < 3 >; digesting the tissue blocks at 37 DEG C to 39 DEG C for 30min to 60min by adopting collagenase with the concentration of more than or equal to 1 percent; carrying out mesenchymal stem cell culture on obtained suspension liquid and digested tissue blocks respectively to obtain the umbilical cord mesenchymal stem cells. According to the preparation method disclosed by the invention, the Wharton's jelly is rapidly digested at relatively high temperature by adopting the high-concentration collagenase; the mesenchymal stem cell culture is carried out on the cell suspension liquid obtained by digestion and the tissue blocks which are not digested respectively; the advantages of a tissue block adherent culture method and an enzyme digestion method are combined, so that more umbilical cord me |
