iPSC Development Service

iPSCs are cells that have been artificially reprogrammed from a somatic state to a pluripotent state. In the field of rare diseases, iPSCs have been used for directed differentiation into various types of cells, and have been used in preclinical projects. Our company offers comprehensive and professional services to construct normal and patient-specific iPSC models in accordance with your needs.

iPSCs Reprogramming

At present, a series of techniques for reprogramming somatic cells into iPSCs have been established. Transgenic and chemical reprogramming are two dominating strategies for iPSCs, for which some researches have provided optimization protocols to improve their reprogramming efficiency.

Transgenic Reprogramming

Patient-derived skin fibroblasts or cells from tissue of disease can be reprogrammed to pluripotent state after ectopic expression of Oct3/4, Sox2, c-Myc, and Klf4. Alternatively, some other transcription factors could be used to replace the above four pluripotency factors, depending on the possible differences in reprogramming efficiency in different cells. To achieve stable expression, each of these pluripotency factors must be inserted into the genome of the cell. Therefore, a variety of transgenic approaches have been applied to induce pluripotent stem cells.

  • CRISPRa system
  • Retroviral vector
  • Lentiviral vector
  • Adenoviral vector
  • Sendai viral vector
  • Episomal plasmid vector
  • Direct delivery of synthetic mRNAs

Chemical Reprogramming

Chemical/small molecule-based reprogramming strategies have shown the advantage of being more efficient. The application of histone deacetylase inhibitor, MAPK/ERK kinase inhibitor or small-molecule cocktail, in combination with transgenic strategies, significantly improves the reprogramming efficiency and shortens the induction time. These strategies have made great progress in the field of rare diseases, including the construction of iPSCs for diseases associated with nervous system, blood, and immune system,etc., for the subsequent basic and preclinical research.

  • Inhibition factors
  • Small molecule cocktail

iPSCs Differentiation

Since iPSCs are pluripotent, these cells can theoretically differentiate into any type of cells involved in rare diseases. For rare diseases, the establishment of patient-derived iPSCs not only solves the problem of cell scarcity, but also allows directional differentiation into any cell type in order to realistically reflect pathological development and drug response. Typically, when a rare disease is caused by mutations in multiple genes, iPSCs is an advantageous operational model platform.

For iPSCs differentiation, introducing specific transcription factors and cultivating in appropriate media are approaches to promote differentiation into the expected cell type. In the study of rare diseases, patient-derived iPSCs have been induced into different cells, such as dopaminergic neurons, cholinergic neurons, and retinal pigment epithelial cells. Then the cells carrying the same genetic background as the patient are used for downstream customized therapy.
