A particulate lyophilized platelet lysate composition suitable for use as a cell culture medium can include growth factors, cytokines, and chemokines released from lysis of source platelets, wherein cellular debris from the source platelets is removed (partially or fully) by filtration. The growth factors, cytokines, and chemokines are lyophilized to form a particulate lyophilized platelet lysate composition.

The present disclosure provides compositions and methods comprising human platelet releasate (hPR), a xeno-free media supplement. The disclosure also relates to a cGMP process for the rapid, efficient and large-scale manufacturing of hPR that may be performed in less than 4 hours. The platelet releasate of the current disclosure prevents gelation of growth media alleviating the need for heparin or other anticoagulants. Mesenchymal stem cells expanded in the presence of platelet releasate have demonstrated superior expansion rates and potency compared to commercial supplements including platelet lysates. The releasate has therapeutic and medical applications. The disclosure also relates to compositions and methods related to platelet-rich fibrin.

The present invention relates to methods for producing immuno-stimulatory autologous dendritic cells. The present invention further relates to the use of such cells for treating patients suffering from hyper-proliferative disease such as cancer.

The present invention relates to production of therapeutic potential WJ-MSCs for clinical purposes. The WJ-MSCs cultured in optimal culture conditions for production of clinical grade WJ-MSCs wherein 4 different culture media which are Media A, Media B, Media C and Media D used to produce 4 types of WJ-MSCs with different therapeutic potential. The WJ-MSCs harvested from Media A has therapeutic potential related to immune, wound healing and cell migration and the WJ-MSCs harvested from Media B has therapeutic potential related to localization, cell proliferation and cell migration. Meanwhile, the WJ-MSCs harvested from Media C has therapeutic potential related to organ development and osteogenesis and the WJ-MSCs harvested from Media D has therapeutic potential related to tissue development, cell signaling and localization.

The disclosure provides a human umbilical cord mesenchymal stem cell sheet comprising one or more layers of confluent human umbilical cord mesenchymal stem cells (hUC-MSCs). The disclosure also provides method for producing hUC-MSC sheets comprising culturing hUC-MSCs in culture solution on a temperature-responsive polymer which has been coated onto a substrate surface of a cell culture support, wherein the temperature-responsive polymer has a lower critical solution temperature in water of 0-80° C.; adjusting the temperature of the culture solution to below the lower critical solution temperature, whereby the substrate surface is made hydrophilic and adhesion of the cell sheet to the surface is weakened; and detaching the cell sheet from the culture support.

The embodiments of the present disclosure provide a cell culture composition and a use thereof, and the cell culture composition includes a culture medium and mitochondria. The cell culture composition including mitochondria can promote cell growth and improve the function of the damaged or aged stem cells, thereby improving overall cell growth.

The embodiments of the present disclosure provide a composition including mitochondria. By providing the mitochondria to cartilage, the composition can improve the mitochondrial function of the chondrocytes in the cartilage so as to increase the repair ability of the chondrocytes and repair the cartilage damage caused by aging of the chondrocytes, thereby achieving the purpose of treating osteoarthritis.

The present invention relates to methods for producing immuno-suppressive dendritic cells. The present invention further relates to the use of such cells for treating patients suffering from autoimmune diseases, hypersensitivity diseases, rejection on solid-organ transplantation and/or Graft-versus-Host disease.

The present invention relates to methods for producing immuno-stimulatory autologous dendritic cells. The present invention further relates to the use of such cells for treating patients suffering from hyper-proliferative disease such as cancer.
