There is provided a method of inducing bone marrow stromal cells to differentiate into bone marrow stromal cell-derived Schwann cells in vitro, comprising the steps of: collecting bone marrow stromal cells from bone marrow and culturing the cells in a standard essential culture medium supplemented with a serum; adding a reducing agent to the culture medium and further culturing the cells; adding a differentiation inducing agent to the culture medium and further culturing the cells; and adding a cyclic AMP-augmenting agent or a cyclic AMP analogue and / or a glial cell differentiation and survival stimulating factor to the culture medium, and further culturing the cells to obtain the bone marrow stromal cell-derived Schwann cells. There are also provided bone marrow stromal cell-derived Schwann cells obtained thereby and a pharmaceutical composition for neural regeneration that comprises them.

The pericardial heart valve replacement (1) is constructed from living tissue of autologous pericardium containing living pericardial interstitial cells (PICs) and a living extracellular matrix (ECM) in the following way: in the first step the size and shape of the patient's native pathological heart valve is determined using real-time three-dimensional transesophageal echocardiography (TEE) or computer tomography (CT angiography) or magnetic resonance imaging (MRI); in the next step a stented (2) or a stentless pericardial heart valve replacement (1) is constructed from a single sheet of living autologous pericardium obtained from the patient; the size and shape of the pericardial heart valve replacement (1) corresponds to the size and shape of the patient's native heart valve and aortic or pulmonary root. The subject matter of the invention also includes the development of a device (5) for the conditioning and modification of the living autologous pericardial heart valve replacement (1) consisting of a ipulsatile pump (6) driving the flow of culture medium in the device (5) to perfuse the cells in the pericardium, a reservoir (7) regulating the fluid capacitance and function of the pericardial heart valve replacement (1), a chamber (8) containing a holder (9) for the placement of the pericardial heart valve replacement (1) during dynamic conditioning, and a gas exchanger (10a, b) for perfusing CO2 into the culture medium. The reservoir (7), the chamber (8) and the gas exchanger (10a, b) are placed in an incubator (11) with an inner atmosphere of air mixed with 5% CO2 and a temperature of 36 to 37° C., the individual components of the device (5) being connected by tubing (12).

Provided herein are isolated populations of kidney cells harvested from differentiated cells of the kidney, wherein cells have been expanded in vitro. The kidney cells may include peritubular interstitial cells of the kidney, and preferably produce erythropoietin (EPO). The kidney cells may also be selected based upon EPO production. Methods of producing an isolated population of EPO producing cells are also provided, and methods of treating a kidney disease resulting in decreased EPO production in a patient in need thereof are provided, including administering the population to the patient, whereby the cells produce EPO in vivo.
