  • Publication number: 20230257735
    Abstract: Provided are methods of adding adapters to nucleic acids. The methods include combining in a reaction mixture a template ribonucleic acid (RNA), a template switch oligonucleotide including a 3? hybridization domain and a sequencing platform adapter construct, a polymerase, and dNTPs. The reaction mixture components are combined under conditions sufficient to produce a product nucleic acid that includes the template RNA and the template switch oligonucleotide each hybridized to adjacent regions of a single product nucleic acid that includes a region polymerized from the dNTPs by the polymerase. Aspects of the invention further include compositions and kits.

  • Publication number: 20220145249
    Abstract: The invention relates to a method of altering a differentiation status of a stem cell by modulating the expression of one or more differentiation factors with a nuclease-deactivated Cas9 (dCas9) fusion protein comprising dCas9 and a transcriptional activator. The method may further include a guide RNA (gRNA) and an activator module comprising RNA-binding protein binding capable of binding to the gRNA. In one embodiment, the dCas9 fusion protein comprises dCas9 and VP64 while the activator module comprises MS2 coat protein and p65. The one or more differentiation factors may comprise PAX6, MITF and OTX2 for differentiation of pluripotent stem cell into retinal pigment epithelium (RPE). Also disclosed are cells comprising the dCas9 fusion protein, gRNA, kits, and method of treating a disease thereof.

  • Patent number: 10865384
    Abstract: This invention relates to a method for inducing or enhancing the differentiation of pluripotent stem cells into cardiomyocyte via casein kinase 1 inhibition said method comprising culturing the stem cells in the presence of a medium comprising a casein kinase 1 inhibitor of the formula (I) or (II) or a stereoisomer, tautomer, or a salt thereof wherein R1, R2 and R3 independently from another represent hydrogen, optionally substituted alkyl, alkenyl, alkynyl, heterocyclyl, heteroaryl or aryl; X represents NR4, O or S; and R4 represents hydrogen, optionally substituted alkyl, alkenyl, alkynyl, heterocyclyl, heteroaryl or aryl. The method can be used in the late phase of stem cell differentiation and in the compounds of formula (I) or (II) in combination with other small molecules can lead to especially high differentiation of stem cells into cardiomyocytes. The invention further relates to novel compounds which can be used in the method of the invention and kits for stem cell differentiation.
