Cell Line Development Service

Cell lines are cell cultures that are genetically modified to become immortal, and infinitely proliferative and passable. In the study of rare diseases, cell lines can be genetically engineered so that their properties meet the desired research for gene function study and drug screening, to circumvent the dilemma of scarce research resources. Our company provides professional services to construct stable cell lines according to your requirements.

Cell Lines for Rare Diseases

The immortalized cells have strong proliferation ability, can be passaged indefinitely, and can obtain a large number of cell resources in a shorter experimental cycle. Additionally, under the same genetic background, the stability of the experimental results can be guaranteed. A variety of cell immortalization methods have been established mainly based on the intervention of exogenous genes.

Commercial cell lines including HEK293T, Hela, K562 and NIH/3T3 have been used as models for various rare diseases. Through genetic engineering, the specific genes of the cell line is mutated or overexpressed to mimic the pathogenesis of the corresponding tissues. Additionally, immortalized cells derived from the same source as the diseased tissue provide a more suitable platform for the mechanistic study of rare diseases.

Potential Targets for Rare Diseases

A large number of rare diseases are caused by the loss of function of specific genes. Knockdown/knockout of specific genes through RNA interference or CRISPR/Cas9 technology leading to the loss of function is one of the essential strategies to study the role of these genes in various biological processes of rare diseases. A typical example is the inactivated mutations in DNA methylation-related genes affecting the epigenome of cells, consequently attributing to some rare diseases.
