108 results about "Umbilical Cord Blood Stem Cell" patented technology

This invention is concerned with stem cells derived from umbilical cord blood serum and a method for growing human embryonic stem cells and adult cells comprising sera separated from clotted umbilical cord blood, including growing and differentiating cord blood stem cells into neural precursors, comprising transdifferentiating CD34+, CD45+ and CD133+ stem cells from mononuclear cells derived from umbilical cord blood to neural precursors. The stem cells obtained from the umbilical cord include pluripotent stem and progenitor cell population of mononuclear cells, and separating pluripotent stem and progenitor cell population of mononuclear cells obtained from the umbilical cord blood. A magnetic cell separator is used to separate out cells which contain a CD marker and then expanding the cells in a medium containing retinoic acid as a differentiating agent supplemented with one or more growth factors BDNF, GDNF, NGF and FGF in presence of cord blood serum. The invention is also concerned with the transplantation and repair of nerve damage, strokes, spinal injury, Parkinson's and Alzheimer's, prepared with a media for culturing umbilical cord blood stem cells in umbilical cord serum.

The invention relates to an umbilical cord blood stem cell cryopreservation box, relates to the field of medical instruments and mainly solves the technical problem that the stem cell freezing effectis affected due to the fact that longer time is consumed when a collection bag on a lower layer in an existing cryopreservation box is taken out. According to the technical scheme, the umbilical cordblood stem cell cryopreservation box comprises a box body, collection bag accommodating mechanisms and position adjusting mechanisms; the box body comprises a box cover and an access port located on one side surface, and the box cover can be opened and closed relative to the access port; each collection bag accommodating mechanism comprises a support plate and a press plate which are arranged in parallel, and the press plate is located above the support plate; each press plate can move relative to the corresponding support plate, an accommodating gap used for accommodating a collection bag isformed between each support plate and the corresponding press plate when the press plate moves to the first position, and a gap port of the accommodating gap is opposite to the access port; each pressplate applies pressure to each collection bag when moving to the second position; the position adjusting mechanisms are matched with the box cover, so that the press plates are located in the first position when the box cover is opened and located in the second position when the box cover is closed.
