Outcomes

The evidence for exosome soft-tissue injection outcomes is extremely limited and primarily confined to preclinical animal studies. The available research focuses on specific applications rather than providing comprehensive clinical data on human patients.

Wound Healing Outcomes

Animal Studies:

Plant-derived exosome injections showed regenerative potential in laser-induced skin wounds in rabbit models (2025)
Plant exosome injections demonstrated measurable effects in tongue wound healing in experimental animals, with histological and immunohistochemical changes documented (2026)

Tendon Repair Outcomes

Preclinical Research:

Schwann cell-derived exosomes (SCDE) promoted tendon repair through modulation of the PTEN/PI3K/Akt signaling pathway in laboratory studies
Specific biomarker changes and pathway activation were documented, though clinical translation remains unestablished

Safety Concerns

Case Reports:

At least one documented case of anaphylaxis following stem cell exosome injection, requiring treatment with 5-fluorouracil and triamcinolone acetonide
This represents a serious adverse event that required medical intervention

Evidence Limitations

The current literature lacks:

Randomized controlled trials in humans
Standardized outcome measures
Long-term safety data
Dose-response relationships
Comparative effectiveness studies

Critical Gap: No clinical trials were identified in major databases, indicating that human efficacy and safety data are not available through rigorous study designs. The available evidence consists primarily of animal models and isolated case reports.
