The formation of new scaffolds to enhance healing magnitude is necessarily required in biomedical applications. Granulation tissue formation is a crucial stage of wound healing in which granulation tissue grows on the surface of a wound by the formation of connective tissue and blood vessels. In the present study, porous hydrogels were synthesized using chitosan incorporating latex of the plant by using a freeze-thaw cycle to stimulate the formation of granulation tissue and angiogenesis in wound healing applications. Structural analysis through Fourier transform infrared (FTIR) spectroscopy confirmed the interaction between chitosan and . Latex extract containing hydrogel showed slightly higher absorption than the control during water absorption analysis. Thermogravimetric analysis showed high thermal stability of the 60:40 combination of chitosan (CS) and as compared to all other treatments and controls. A fabricated scaffold application on a chick chorioallantoic membrane (CAM) showed that all hydrogels containing latex extract resulted in a significant formation of blood vessels and regeneration of cells. Overall, the formation of connective tissues and blood capillaries and healing magnitude decreased in ascending order of concentration of extract.
在生物医学应用中,需要形成新的支架来增强愈合效果。肉芽组织的形成是伤口愈合的关键阶段,在此阶段,通过结缔组织和血管的形成,肉芽组织在伤口表面生长。在本研究中,通过使用冷冻-解冻循环,使用壳聚糖结合植物胶乳合成了多孔水凝胶,以刺激伤口愈合应用中的肉芽组织形成和血管生成。通过傅里叶变换红外(FTIR)光谱的结构分析证实了壳聚糖和胶乳之间的相互作用。水吸收分析表明,含有胶乳提取物的水凝胶的吸收略高于对照。热重分析表明,与所有其他处理和对照相比,壳聚糖(CS)和胶乳的 60:40 组合具有更高的热稳定性。在鸡胚绒毛尿囊膜(CAM)上进行支架应用表明,所有含有胶乳提取物的水凝胶都导致血管的显著形成和细胞的再生。总的来说,结缔组织和毛细血管的形成以及愈合效果按提取物浓度的升序依次降低。
