StemRIM


Biotechnology company developing regeneration‑inducing therapeutics that pharmacologically mobilize and recruit a patient’s own mesenchymal stem/stromal cells to sites of tissue damage. R&D activities include peptide engineering derived from protein functional domains, ex vivo autologous mesenchymal stromal cell gene‑modified therapies, preclinical in vivo efficacy testing, mechanistic omics studies, and early‑ to mid‑stage clinical development for rare and difficult‑to‑treat diseases.

Products

Systemic HMGB1‑derived fragment peptide therapeutic (intravenous)

Synthetic peptide based on a functional fragment of an HMGB1 protein domain intended to mobilize bone‑marrow progenitors into peripheral blood and promote accumulation at sites of tissue injury to enhance regeneration; progressed through non‑clinical models and clinical studies across multiple indications.

Next‑generation systemic regenerative peptide candidates

Artificially designed systemic peptides developed using domain‑focused design and MSC‑induction screening methods to induce endogenous progenitor mobilization and regenerative responses across tissue types.

Locally administered regenerative peptide formulation

Protein/peptide formulation designed for local administration to injured tissue to enhance recruitment and retention of endogenous progenitors in localized lesions.

Autologous MSC‑based ex vivo gene therapy workflow

Autologous mesenchymal stromal cell gene therapy process involving isolation of patient MSCs, ex vivo gene introduction and expansion, and reinfusion to achieve sustained therapeutic gene expression for inherited connective tissue/dermal disorders.


Services
