Clinical Trials

Background:

Cell therapy is a promising strategy for enhancing recovery in stroke survivors.
Despite preclinical success, clinical translation of cell therapy for stroke remains challenging.

Purpose of the Study:

To review major clinical trials of cell therapy for stroke.
To highlight the mechanistic shift in cell therapy approaches for stroke.
To discuss the potential of both cell replacement and neuromodulatory mechanisms for future efforts.

Main Methods:

Systematic review of major clinical trials involving cell therapy for stroke.
Analysis of the intended mechanisms of action in early versus later trials.
Discussion of the feasibility and potential of cell replacement strategies.

Main Results:

Early cell therapy trials for stroke primarily aimed at replacing damaged neurons.
Later trials shifted focus to the neuromodulatory effects of stem cells.
Both cell replacement and neuromodulation are considered viable mechanisms for stroke recovery.

Conclusions:

Understanding the mechanistic evolution of cell therapy trials is crucial for future research.
Further investigation into cell replacement strategies is warranted alongside neuromodulatory approaches.
Optimizing cell therapy for stroke requires a nuanced approach considering diverse mechanisms of action.
