CULTURE MEDIUM FOR GROWTH OF NEURAL STEM CELLS
A culture medium and a method to efficiently grow neuronal stem cells. The culture medium includes FGF-2, EGF, and a proteoglycan, where the proteoglycan is preferably a chondroitin sulfate-type proteoglycan, and more preferably, a salmon nasal cartilage-derived proteoglycan. The culture medium is capable of promoting formation of neurospheres.
METHODS FOR OVERPRODUCING PROTOPORPHYRIN IX IN ALGAE AND COMPOSITIONS THEREFROM
Provided herein are compositions and processes for producing compositions from an algae that overproduces protoporphyrin IX (PPIX). Also provided are methods of growing PPIX overproducing algae, methods of isolating PPIX-containing portions from algae cultures and compositions and methods of making food products with PPIX produced by algae. Provided herein are strains and methods to select strains that overproduce PPIX. Also provided are compositions, including edible compositions that include PPIX produced from algae. Specifically, the algal strain over-producing PPIX is an engineered strain of The algal biomass may be used for preparing meat analogues wherein the PPIX compound imparts a meat-like colour and flavour.
Method of producing oil containing polyunsaturated fatty acids by using <i>Schizochytrium </i>sp
Provided is a method of producing an oil containing polyunsaturated fatty acids by using Schizochytrium sp. The method comprises: performing fermentation using Schizochytrium sp.; resuspending the resultant cells after fermentation in water, adding cellulase and neutral protease for enzymolysis; mixing the enzymatic hydrolyzate with n-hexane, shaking, extracting, centrifuging, and collecting the n-hexane phase; concentrating the n-hexane phase under reduced pressure to remove the n-hexane, and drying to obtain an oil; performing a first crystallization and a second crystallization, and then performing cold filtration to obtain a liquid oil after the second crystallization; and subjecting the liquid oil to deacidification and decolorization. By regulating fermentation conditions and conducting concentration processing on polyunsaturated fatty acids, the content of eicosapentaenoic acid in the Schizochytrium sp. is increased to more than 12%, and the obtained oil is rich in docosahexaenoic acid, docosapentaenoic acid and eicosapentaenoic acid.
Growth and Survival Compositions for Cells Capable of Producing Antibodies and Methods Related Thereto
This disclosure relates to growth media and environments for in vitro culturing of cells that produce or are capable of producing antibodies. In certain embodiments, the media comprises IL-6, fibronectin, and typically a saccharide. In certain embodiments, the disclosure contemplates cell culture compositions comprising IL-6 and fibronectin that are derived from proteins secreted from mesenchymal stromal/stem cells (MSCs). In certain embodiments, the disclosure contemplates enclosures comprising culture compositions disclosed herein that are in ambient air or optionally in an environment wherein oxygen is absent or at a low concentration.
USE OF CELL MEMBRANE-BOUND SIGNALING FACTORS
Disclosed herein are compositions comprising complexes of cyclodextrins and lipid-modified stem cell proteins. Also disclosed are topical compositions the complexes. Methods of using the compositions for the therapeutic purposes are also disclosed as well as methods of producing the compositions.
Cartilage and bone repair and regeneration using postpartum-derived cells
Cells derived from postpartum tissue and methods for their isolation and induction to differentiate to cells of a chondrogenic or osteogenic phenotype are provided by the invention. The invention further provides cultures and compositions of the postpartum-derived cells and products related thereto. The postpartum-derived cells of the invention and products related thereto have a plethora of uses, including but not limited to research, diagnostic, and therapeutic applications, for example, in the treatment of bone and cartilage conditions.
Extracellular matrix compositions for the treatment of cancer or immunological diseases
The present invention is directed to methods of inhibiting cancer cell growth or proliferation by contacting the cancer cell with an extracellular matrix (ECM) composition. Also provided are methods of delivering a chemotherapeutic agent to a cancer cell by contacting a cancer cell with an extracellular matrix composition containing a chemotherapeutic agent. Also provided are compositions containing ECM and a chemotherapeutic agent.
Lactobacillus Gasseri HMV18 and Exocrine Protein and Application Thereof
The present disclosure relates to the technical field of microorganisms, in particular to Lactobacillus gasseri HMV18 and an exocrine protein and an application thereof. The Lactobacillus gasseri HMV18 is preserved in the China Center for Type Culture Collection on Jul. 11, 2019 with a preservation number of CCTCC NO: M 2019538, and a preservation address of Wuhan University, Wuhan, China. The protein extracted from the Lactobacillus gasseri HMV18 has antibacterial and anti-tumor effects, but basically has no effect on normal myocardial cells, so the Lactobacillus gasseri HMV18 can be applied to preparation of antibacterial and anti-tumor products.
CELL DIFFERENTIATION MEDIUM COMPOSITION, HIGH SECRETION INSULIN-PRODUCING CELLS AND PREPARATION METHOD THEREOF
The present invention relates to a cell differentiation medium composition, a high secretion insulin-producing cells and a preparation method thereof. The high secretion insulin-producing cells obtained by using the cell differentiation medium composition to induce stem cell differentiated under specific conditions can secrete a large amount of insulin in a short time, and when the high-secreting insulin-producing cells are transplanted into the human body, they are not easy to be swallowed by macrophages, which can improve the survival rate of the insulin-producing cells and prolong the time of insulin secretion thereby.
COMPOSITIONS AND METHODS FOR DIFFERENTIATING STEM CELLS INTO NK CELLS
The disclosure features methods and compositions for differentiating stem cells into hematopoietic stem and progenitor cells (HSPC) and/or Natural Killer (NK) cells. The methods and compositions described herein are used to differentiate stem or progenitor cells having at least one gene-edit that is maintained in the differentiated cell. Also provided are differentiated cells produced using the methods and compositions described herein for therapeutic applications.
