The invention relates to the technical field of regenerative medicine and discloses a method for adjusting and controlling in vitro three-dimensional directed differentiation of stem cells. The method includes following steps: embedding Stem cells into calcium alginate micro gel beads containing chondroitin sulfate, adding an inductive differentiation culture liquid, adjusting and controlling the in vitro directed differentiation of the stem cells by changing a mass ratio between the sodium alginate and the chondroitin sulfate during the preparation of the micro gel beads, dissolving the calcium alginate micro gel beads in a sodium citrate solution after the differentiation process being finished, and then obtaining pure differentiation cells. The method is simple in operation and low in cost, the calcium alginate micro gel beads containing chondroitin sulfate can simulate an in vivo three-dimensional extracellular matrix so that a three-dimensional directed differentiating microenvironment which approximates an in vivo microenvironment is supplied for the stem cells, thereby improving directed differentiation efficiency and a biological function of the stem cells. The method plays an important role in applications of regenerative medicine.

The present invention provides a method for enhancing immune cell function by activating various immune cells ex vivo and provides immune cells with enhanced function. The invention further provides an immune-related cell multifunctionality evaluation method. A biguanide antidiabetic drug selected from metformin, phenformin, and buformin is capable of enhancing immune cell multifunctionality by increasing CD8+T cells having a high ability to produce IL-2, INFα, and IFNγ. The immune-related cell multifunctionality may be evaluated by comparing immune cells treated with a biguanide antidiabetic drug selected from metformin, phenformin, and buformin, with control immune cells untreated with the biguanide antidiabetic drug. When the multifunctionality of immune cells treated with the biguanide antidiabetic drug selected from metformin, phenformin, and buformin is determined to be significantly increased compared with the control, it can be evaluated that the sensitivity of the immune cells to the therapeutic agent is improved.
