/ 01 Immune Privilege

How Dezawa MuseCells® avoid immune rejection.

Dezawa MuseCells® carry a naturally immune-privileged profile — allowing for allogeneic (donor-based) administration without triggering rejection or requiring immunosuppressive drugs.1

Immune MarkerMechanism
HLA-G+Inhibits natural killer (NK) cells and cytotoxic T-cells, mimicking immune tolerance seen during pregnancy.
IDO+Converts tryptophan into kynurenine, which inhibits T-cell activation and dampens immune response at inflammation sites.
HLA-DRAbsence of this antigen prevents activation of helper T-cells, reducing the risk of adaptive immune targeting.

/ 02 Safety Profile

Key safety differentiators vs conventional models.

Four safety attributes that distinguish Dezawa MuseCells® from conventional cell therapies — each backed by published evidence.

Safety AttributeDezawa MuseCells®
Tumor formationNone observed in vivo + preclinical2
HLA matching requiredNo3
ImmunosuppressionNot required in any human trial3
Pluripotency methodNatural (no reprogramming)4
Allogeneic immunogenicityBroader MSC field: ~15% of MSC patients in DSA-measurement studies developed donor-specific antibodies.5 Muse cells: HLA-G+ immune privilege — no DSA correlation with safety outcomes.

/ 03 Published Findings

What studies show about Dezawa MuseCells®.

Five characteristics that distinguish this cell line in published literature.

Five traits that
define the DMC.

Scroll ↓ to read
  1. Trait · 01

    Pluripotent-like. Dezawa MuseCells® spontaneously differentiate into ectoderm, mesoderm, and endoderm lineages in vivo.

  2. Trait · 02

    Non-tumorigenic. They do not form teratoma — even in long-term immunodeficient mouse models.

  3. Trait · 03

    Stress-enduring. They survive harsh environments (hypoxia, serum deprivation) that other stem cells cannot.

  4. Trait · 04

    Immune tolerance. HLA-G+, IDO+, HLA-DR profile enables allogeneic use without immunosuppressants.

  5. Trait · 05

    Stable karyotype. Dezawa MuseCells® maintain chromosomal integrity and low telomerase, minimizing mutation risk.

Backed by 120+ global publications — one of the strongest evidence bases in regenerative medicine.

/ 04 vs Traditional MSCs

How Dezawa MuseCells® differ from traditional MSCs.

Dezawa MuseCells® and Dezawa MuseExosomes® have been studied primarily in Japan and, in published research, have demonstrated advantages over traditional MSCs across pluripotency, stress resistance, and safety.
