Трансплантация индуцированных плюрипотентных стволовых клеток, полученных Мезоангиобласт-как миогенные прогениторы в мышиных моделях мышечной регенерации

Overview

This protocol outlines the evaluation of myogenic potential of induced pluripotent stem cell (iPSC)-derived muscle progenitors in mouse models of muscle regeneration. It includes transplantation techniques and functional assessments to measure engraftment and differentiation.

Key Study Components

Area of Science

• Stem Cell Biology
• Muscle Regeneration
• Cell Therapy

Background

• Induced pluripotent stem cells (iPSCs) can differentiate into various cell types.
• Myogenic progenitors derived from iPSCs are promising for treating muscular dystrophies.
• Understanding engraftment and functional contribution is crucial for therapeutic applications.
• This study focuses on both acute and chronic muscle regeneration models.

Purpose of Study

• To evaluate the effectiveness of transplantation methods.
• To measure the functional improvement in dystrophic mouse models.

Methods Used

• In vitro assessment of myogenic potential of iPSC-derived cells.
• Intramuscular injection of cells for transplantation.
• Microsurgical injection via the femoral artery as an alternative method.
• Immunofluorescence and histology assays to evaluate engraftment and functionality.

Main Results

• Successful engraftment of iPSC-derived muscle progenitors in host muscles.
• Functional amelioration of the dystrophic phenotype observed in treated animals.
• Histological analysis confirmed differentiation and integration of donor cells.
• In vitro assessments correlated with in vivo outcomes.

Conclusions
