  • Patent number: 10590393
    Abstract: In one embodiment, the present invention is a method of creating a fully-human blood-brain barrier (BBB) model, comprising the steps of (a) obtaining a mixture of neural cells and brain microvascular endothelial cells (BMECs), wherein the neural cells and BMECs that comprise the mixture were produced from the differentiation of human pluripotent stem cells (hPSCs); (b) purifying BMECs from the mixture of neural cells and BMECs of step (a); and (c) co-culturing the purified BMECs with a cell type selected from the group consisting of pericytes, astrocytes and differentiated neural progenitor cells (NPCs), wherein a blood brain barrier model is created.

  • Patent number: 9168329
    Abstract: The present invention is directed to the design, synthesis and use of various ?-peptides exhibiting antifungal activity. The ?-peptides are relatively short in length, adopt globally amphiphilic conformations, and cause little lysis of human red blood cells at concentrations that kill Candida albicans, a common human fungal pathogen.

  • Patent number: 8956867
    Abstract: A three-dimensional microwell system that supports long term pluripotent cell culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured pluripotent cells remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel®-coated, tissue culture-treated polystyrene dishes. Microwell-cultured pluripotent cells maintain pluripotency, differentiating to each of the three embryonic germ layers. Pluripotent cell aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain pluripotent cell growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct pluripotent cell differentiation by generating monodisperse EBs of a desired size and shape.
