Abstract: The present invention belongs to the field of cell transplantation. Particularly, the present invention provides a method of producing neurons for treating injuries with the loss of neuron function from stem cells, wherein the stem cell is a human derived mesenchymal stem cell, preferably human derived placental mesenchymal stem cell, bone marrow mesenchymal stem cell, adipose mesenchymal stem cell and liver mesenchymal stem cell. The present invention also provides the uses of said method and the nerve cells produced by said method in the preparation of medicines for treating injuries with the loss of neuron function and in the treatment of injuries with the loss of neuron function. The present invention further provides a method of treating injuries with the loss of neuron function.

Abstract: The present invention relates to a method for processing human placental cell sample, a human placental cell sample obtained according to said method for processing human placental cell sample, a human placental cell bank, a method for banking human placental cells, a method for searching human placental cell sample in said human placental cell bank according to the present invention, a method for preparing human cord blood serum, use of human placental cells obtained by said method for processing human placental cell sample or human placental cell bank established by said method for banking human placental cells in treating human dysfunction and diseases due to cell injury or cell malfunction, as well as a method for treating human dysfunction and diseases due to cell injury or cell malfunction.
