摘要： PROBLEM TO BE SOLVED: To provide a base material for generating cell tissue which satisfies the following (1) and (2): (1) to be excellent in safety and biocompatibility without using a chemical crosslinking agent, chemical modifying agent, etc., and (2) to be made usable for tissue regeneration by culturing cartilage cells and stem cells within and/or on the surface of the base material.
SOLUTION: The base material for regenerating the cell tissue contains a hyaluronic acid gel which consists of a hyaluronic acid, is not substantially modified by the chemical crosslinking agent or the chemical modifying agent and is hardly soluble in a neutral aqueous solution.

摘要： PROBLEM TO BE SOLVED: To provide a method for separating and collecting mesenchymal stem cells to utilize them for the regenerative treatment of a tissue, etc., and for the preparation of mammalian cells used for the regeneration and/or restoration of the tissue, safe for a collected parent body and also easy for collection, and also a practical method for preparing cells for transplant by using the collected mesenchymal mast cells. SOLUTION: This method for collecting mesenchymal stem cells capable of collecting the cells by using a method for separating and collecting the cells from an oral cavity tissue by a simple operation of requiring a minimum exfoliation and incision of the skin and muscle, not imposing a burden to the collected parent body, safely and simply collecting the necessary amount of the cells maintaining an excellent differentiation potency. Further, the use of the mesenchymal stem cells is provided by culturing and differentiation-inducing the separated and collected mesenchymal stem cells to prepare cells used for the regeneration and/or restoration of a tissue having high differentiation potency, and transplanting the prepared cells to the defective part and/or part for restoration such as the bone, cartilage, periodontal tissue, etc., to regenerate and/or restore the tissues.

摘要： PROBLEM TO BE SOLVED: To provide a new method for culturing a mesenchymal stem cell capable of obtaining extremely larger amount of the mesenchymal stem cell than a conventional method under practical conditions aiming the use of the mesenchymal stem cell for a regenerative care of a tissue. SOLUTION: It was found that, by culturing a mesenchymal stem cell in the presence of an extracellular substrate of basement membrane cells, for example, by culturing a mesenchymal stem cell on a culture dish coated with the extracellular substrate of basement membrane cells, the mesenchymal stem cell grows at an extremely high speed, it can keep a differential ability to an osteoblast, a chondrocyte or a fat cell, it can be effectively grown even with a serum of a low concentration, it can be cultured by using human serum, and further, excellent differentiation-inducing culturing is possible. Further, even in the case where culturing is carried out in a lower concentration of serum, growth ability and differential ability can be kept by adding various kinds of additives to the culture medium.
