  • Patent number: 12378527
    Abstract: The present disclosure describes methods of differentiating cardiomyocyte progenitor cells and mature cardiomyocyte cells from pluripotent stem cells. The methods may include differentiating pluripotent stems cells on a substrate including (i) laminin-511 or 521 and (ii) laminin 221. The mature cardiomyocyte cells produced by the method may form a human heart muscle cell line for use in regenerative cardiology.
    Type: Grant

  • Publication number: 20220041980
    Abstract: The present disclosure describes methods of maintaining the phenotype of differentiated cells. Generally, the natural environment of the body is replicated for the differentiated cell. The differentiated cell is plated on a cell culture substrate comprising a laminin, such as laminin-521 or laminin-511. The substrate may also contain a cadherin. This maintains the phenotype of the differentiated cell.

  • Publication number: 20170342378
    Abstract: The present disclosure is related to methods for forming a stem cell bank. The methods include obtaining a first stem cell from a multi-cell fertilized embryo, expanding the first stem cell into two or more descendant stem cells, and storing at least one of the descendant stem cells to form the stem cell bank. Also disclosed is a kit that can be used for making the stem cell bank during in vitro fertilization. If desired, the HLA serotype of the stem cells can be determined prior to storage.

  • Patent number: 9828630
    Abstract: The present disclosure relates to the use of laminin-521. Laminin-521 can maintain stem cells in vitro pluripotency, enable self-renewal, and enable single cell survival of human embryonic stem cells. When pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in the absence of differentiation inhibitors or feeder cells, the embryonic stem cells proliferate and maintain their pluripotency. Methods of enhancing genetic diagnosis by expanding a single stem cell on laminin-521 prior to PCR amplification are disclosed herein.
