Summary
Engineered amniotic fluid-derived mesenchymal stem cell-secreted molecules (afMSC-SMs) offer a versatile, cell-free approach for skin regeneration. This bioactive material supports cell growth and enables wound healing and hair regrowth applications.
Area of Science:
- Regenerative Medicine
- Biomaterials Science
- Stem Cell Biology
Background:
- Stem cells are crucial in regenerative engineering.
- Developing efficient and versatile bioactive materials is essential for skin regeneration.
- Current methods for cell expansion and tissue engineering have limitations.
Purpose of the Study:
- To explore the feasibility of engineering amniotic fluid-derived mesenchymal stem cell-secreted molecules (afMSC-SMs) as a bioactive material for skin regenerative medicine.
- To assess the efficacy of afMSC-SMs in supporting keratinocyte function and epithelial reconstitution.
- To demonstrate the potential of afMSC-SMs in wound healing and hair regrowth applications.
Main Methods:
- Amniotic fluid-derived mesenchymal stem cell-secreted molecules (afMSC-SMs) were obtained via ethanol precipitation.
- The effect of afMSC-SMs on primary human keratinocytes (pKCs) in a xeno-free environment was evaluated.
- afMSC-SMs were formulated into injectable hydrogels and nanogels for transdermal delivery.
Main Results:
- afMSC-SMs preserved the self-renewal and differentiation potential of pKCs.
- afMSC-SMs facilitated the reconstitution of a stratified epithelium sheet on human dermal fibroblasts.
- Injectable hydrogel and nanogel systems demonstrated potential for wound healing and hair regrowth, respectively.
Conclusions:
- afMSC-SMs represent a promising cell-free therapeutic material for skin regenerative medicine.
- This approach offers advantages in manufacturing, scalability, formulation, and safety compared to cell-based therapies.
- afMSC-SMs provide a versatile toolbox for advancing cell-free regenerative medicine in clinical settings.

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

2.5K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
