Cell therapy holds great promise for cutaneous wound treatment but presents practical and clinical challenges, mainly related to the lack of a supportive and inductive microenvironment for cells after transplantation. Main: This review delineates the challenges and opportunities in cell therapies for acute and chronic wounds and highlights the contribution of biofabricated matrices to skin reconstruction. The complexity of the wound healing process necessitates the development of matrices with properties comparable to the extracellular matrix in the skin for their structure and composition. Over recent years, emerging biofabrication technologies have shown a capacity for creating complex matrices. In cell therapy, multifunctional material-based matrices have benefits in enhancing cell retention and survival, reducing healing time, and preventing infection and cell transplant rejection. Additionally, they can improve the efficacy of cell therapy, owing to their potential to modulate cell behaviors and regulate spatiotemporal patterns of wound healing.
The ongoing development of biofabrication technologies promises to deliver material-based matrices that are rich in supportive, phenotype patterning cell niches and are robust enough to provide physical protection for the cells during implantation.
细胞疗法在皮肤伤口治疗方面具有巨大潜力,但也面临实际和临床挑战,主要与移植后细胞缺乏支持性和诱导性微环境有关。主要内容:本综述阐述了急性和慢性伤口细胞治疗中的挑战与机遇,并强调了生物制造基质对皮肤重建的贡献。伤口愈合过程的复杂性要求开发出在结构和组成上与皮肤细胞外基质特性相当的基质。近年来,新兴的生物制造技术已显示出制造复杂基质的能力。在细胞治疗中,基于多功能材料的基质在增强细胞保留和存活、减少愈合时间、预防感染和细胞移植排斥方面具有优势。此外,由于它们具有调节细胞行为和调控伤口愈合时空模式的潜力,还可以提高细胞治疗的效果。
生物制造技术的不断发展有望提供基于材料的基质,这些基质富含支持性、表型模式化的细胞龛,并且足够坚固,能够在植入过程中为细胞提供物理保护。
