Self-assembled rosette nanotubes and poly(2-hydroxyethyl methacrylate) hydrogels promote skin cell functions

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Nanotechnology

Background:

• Next-generation wound healing materials require active stimulation of cellular adhesion and proliferation for skin regeneration.
• Rosette nanotubes (RNTs) are novel self-assembling nanomaterials with properties mimicking natural skin structures like collagen and keratin.
• RNTs have demonstrated efficacy in various tissue engineering applications, including bone and cartilage regeneration.

Purpose of the Study:

• To investigate the potential of incorporating TBL RNTs into poly(2-hydroxyethyl methacrylate) (pHEMA) hydrogels for enhanced skin regeneration.
• To evaluate the effect of TBL RNTs on keratinocyte and fibroblast proliferation in vitro.
• To assess the cytocompatibility, solidification, and mechanical properties of RNT-modified hydrogels for wound healing applications.

Main Methods:

• Coating pHEMA hydrogels with TBL rosette nanotubes (RNTs).
• Conducting in vitro studies to assess keratinocyte and fibroblast proliferation on coated and uncoated hydrogels.
• Evaluating the cytocompatibility, solidification, and mechanical properties of the modified hydrogels.

Main Results:

• For the first time, TBL RNTs significantly increased keratinocyte and fibroblast proliferation on pHEMA hydrogels compared to uncoated controls.
• The TBL RNTs exhibited optimal cytocompatibility, solidification, and mechanical properties suitable for wound healing applications.

Conclusions:

• TBL RNTs hold significant promise as a component in advanced wound healing materials.
• The enhanced cellular proliferation observed suggests that TBL RNTs can actively promote skin regeneration.
• Further research into TBL RNTs is warranted for their development in clinical wound healing applications.
