StemEdit iMSC B2M/CIITA DKO ReproMSC14
RCRP057
Brand: StemRNA™
ReproMSC14 are ready-to-use Human Mesenchymal Stem Cells (MSCs, also called Mesenchymal Stromal Cells or Medicinal Signaling Cells) generated from one of our StemRNA™ Clinical Pilot lines, RPC-LLF-34-F3 (established from fibroblasts using the StemRNA Reprogramming Technology), containing knockouts of both alleles of the B2M and CIITA genes.

Ready-to-use, Research-Grade Human iPSC-derived Mesenchymal Stem Cells (iMSCs) bearing an HLA Class I and II double knockout
Repro MSC14 were generated from StemEdit hiPSC B2M/CIITA DKO (Cat. No. RCRP052), a gene-edited version of one of our StemRNA™ Clinical Pilot lines, RPC-LLF-34-F3 (established from fibroblasts using the StemRNA Reprogramming Technology). The analogous wild-type iMSCs line (Repro MSC10 iPSC-derived MSCs (iMSCs), Phenol Red-Free, Cat. No. RCRP038) is also available.
ReproMSC14 cells do not contain Phenol Red, making them ideal for exosome research.
iPSC-derived MSCs, sometimes called iMSCs, offer several advantages over primary MSCs, including a minimally invasive collection process and high proliferative capacity, and they are good candidates for gene editing. Find out more about their potential therapeutic advantages in our recent blog post "The Therapeutic Advantage of Induced Pluripotent Stem Cells-Derived Mesenchymal Stem Cells (iMSCs)".
ReproMSC14 cells feature:
- Easy access to hypoimmune MSCs from a reproducible source.
- Immediate thawing into Phenol Red-free MSC NutriStem XF Culture medium (Cat. No. 01-0007) on vitronectin or MSC Attachment Solution (Cat. No. 05-0063) with easy conversion to other standard MSC Media.
NOTE:
These iMSC cell lines are developed and supplied for Research Use Only (RUO). They are not intended for clinical or therapeutic applications. However, the iPSC clone from which these iMSCs were derived has a clinical-grade iPSC counterpart that is suitable for clinical gene editing and downstream clinical development. If you require material for translational or clinical programs, please see Clinical Stem Cell Services or Contact Us for more information.

The Role of B2M and CIITA
In humans, the B2M protein is required for the presentation of HLA proteins A-G on the cell surface. Disruption of the B2M gene reduces T-cell activation and interferes with the T-cell-mediated immune response through inhibition of Class I HLA signaling. CIITA regulates the expression of the HLA Class II complex. Knocking out CIITA leads to reduced activity of HLA Class II and suppression of the immune response.
