摘要:
An engineered cardiac tissue, a mold for forming an engineered cardiac tissue, and a method of forming an engineered cardiac tissue are provided. The engineered cardiac tissue includes a plurality of induced pluripotent stem cell-derived cardiac cells arranged in a configuration suitable for implantation onto the surface of a heart. The method of forming an engineered cardiac tissue includes providing a mold including an outer surface, pouring a cell solution onto the outer surface of the mold, and forming the engineered cardiac tissue from the cell solution, the engineered cardiac tissue having a geometry corresponding to a geometry of the mold. Methods of treating a myocardial infarction are further provided and include implanting an engineered cardiac tissue onto the heart of a subject.
摘要:
The disclosure relates to in vitro cultures of human hepatocytes, and in particular co-cultures systems including human hepatocytes, non-parenchymal cells, and human endothelial cells, and the use of the co-cultures in developing and screening drugs.
摘要:
Compositions comprising endothelial cells (ECs) differentiated from induced pluripotent stem cells (iPSC) that overexpress Sirtuin 1 (SIRT1) are disclosed. Further disclosed are methods of preparation of the compositions, and methods for treating a subject comprising administering transplatanbe cells, tissue, or organ comprising the iPSC-derived ECs overexpressing SIRT1, as well as methods of testing an agent for therapeutic efficacy and toxicity using the compositions.
摘要:
Compositions for and methods of improving wound healing are disclosed, including compositions for and methods of treating chronic wounds, and compositions for the inhibition and treatment of necrosis and extended quiescence that result in cellular necrosis instead of normal proliferation. The compositions include hydroxytyrosol, oleuropein, or a combination of hydroxytyrosol and oleuropein with endothelial cells. The invention further encompasses methods involving administration of these compositions.
摘要:
A method of promoting lymphatic endothelial cell (LEC) specification is disclosed. The method comprising upregulating the activity of Wnt canonical pathway in stem cells and/or vascular progenitor cells and/or angioblasts, thereby promoting LEC specification. Methods of inducing lymphangiogenesis are also disclosed. Pharmaceutical compositions and methods of treatment are also disclosed.
摘要:
The present invention involves implants suitable for surgical implantation into subjects. In some embodiments the implants comprise a biocompatible scaffold material and blood vessels containing engineered endothelial cells - such as E4ORF1+ engineered endothelial cells or engineered endothelial cells that express certain marker molecules. The present invention provides implants, methods for preparing such implants, and methods of treatment utilizing such implants.
摘要:
This disclosure provides a method for improving maturation of an arteriovenous fistula (AVF) in a patient in need of hemodialysis, which method entails applying a solution to the internal wall of a lumen of an AVF; and restoring or initiating blood flow in the AVF, wherein the solution comprises an effective amount of a synthetic proteoglycan comprises a glycan having from about 1 to about 80 collagen-binding peptide(s) bonded to the glycan. Also provided are methods for preparing a vascular graft for a bypass surgery, comprising contacting the internal wall of a section of a blood vessel with a solution comprising an effective amount of the synthetic proteoglycan.
