Abstract: Co-culture of isolated human induced pluripotent stem cell (iPSC)-derived endothelial and smooth-muscle progenitor cells results in the formation of cellular spheroids having capillary-like structures (referred to herein as ‘capillary fragments’) at their core. Bioprinting of these spheroids into scaffold-free tissue constructs facilitates the development of microvasculature within the engineered tissue. Methods of using these bioprinted engineered tissues for cell therapy are also disclosed.

Abstract: Methods are provided for the isolation, expansion, enrichment, and transplantation of endothelial stem cells from blood vessels and induced pluripotent stem cells via the use of ABCG2 cell surface marker. The ability of the endothelial stem cells to expand in vitro and be subsequently implanted in vivo to generate new blood vessels provides a therapeutic hope for patients with numerous cardiovascular disorders (peripheral arterial disease, critical limb ischemia, ischemic retinopathies, acute ischemic injury to kidney, and myocardial infarction) where the lack of sufficient blood vessel forming ability in the patient limits their regenerative capacity.

Abstract: The present disclosure provides compositions and methods for the treatment or prophylaxis of a perfusion disorder, such as ischemia and/or reperfusion injury, in a subject's organ, tissue or extremity by preserving or improving endothelial function, reducing vascular injury, and/or promoting vascular repair. The disclosed compositions comprise endothelial colony-forming cells or a serum-free composition comprising chemically defined media conditioned by endothelial colony-forming cells.

Abstract: The present disclosure relates generally to methods and compositions useful in cell and tissue biology and therapeutics. In particular, an in vitro method for differentiating pluripotent stem cells into KDR+NCAM+APLNR+ mesoderm cells and/or SSEA5?KDR+NCAM+APLNR+ mesoderm cells is provided. The disclosed mesoderm cells may be used to generate blood vessels in vivo and/or further differentiated in vitro into endothelial colony forming cell-like cells (ECFC-like cells). Purified human cell populations of KDR+NCAM+APLNR+mesoderm cells and ECFC-like cells are provided. Test agent screening and therapeutic methods for using the cell populations of the present disclosure are provided.

Abstract: The present invention generally relates to methods of preventing methionine oxidation in immunoconjugates. The present invention also relates to pharmaceutical compositions of immunoconjugates in which the amount of methionine oxidation is minimized.

Abstract: Parallel reactor systems for synthesizing materials are disclosed. The reactor systems may be suitable for synthesizing materials produced from corrosive reagents. Methods for preparing materials by use of such parallel reactor systems are also disclosed.

Abstract: Materials and methods are disclosed for controlling vasculogenesis using building blocks of a collagen matrix and endothelial colony forming cells (ECFC). The building blocks may be isolated by fractionating an acid soluble Type I collagen. The building blocks comprising monomers and/or oligomers may be recombined in desired ratios to alter the matrix microenvironment and to influence ECFC behavior.

Abstract: A hierarchy of endothelial colony forming cells (EPCs) was identified from mammalian cord blood, umbilical vein and aorta. A newly isolated cell named high proliferative potential endothelial colony forming cell (HPP-ECFC) was isolated and characterized. Single cell assays were developed that test the proliferative and clonogenic potential of endothelial cells derived from cord blood, or from HUVECs and HAECs. EPCs were found to reside in vessel walls. Use of a feeder layer of cells derived from high proliferative potential-endothelial colony forming cells (HPP-ECPCS) from human umbilical cord blood, stimulates growth and survival of repopulating hematopoietic stem and progenitor cells. Stimulation of growth and survival was determined by increased numbers of progenitor cells in in vitro cultures and increased levels of human cell engraftment in the NOD/SCID immunodeficient mouse transplant system.

Abstract: Methods and reagents for the installation of click chemistry handles on target proteins are provided, as well as modified proteins comprising click chemistry handles. Further, chimeric proteins, for example, bi-specific antibodies, that comprise two proteins conjugated via click chemistry, as well as methods for their generation and use are disclosed herein.
