概括

软化氨酸 (HA) 和富血小板血 (PRP) 配方提供了改善的稳定性和受控释放的生长因子,用于组织再生. 这些新的HA/PRP产品在伤口愈合应用中表现有前途,提供增强的细胞增殖和迁移.

科学领域:

再生医学是一种再生医学.
生物材料科学生物材料科学
组织工程是组织工程.

背景情况:

富血小板血 (PRP) 是一种用于再生医学的生物产品,但其临床应用因需要立即准备而受到限制.
开发一种稳定,现成的PRP配方,并控制生长因子释放,对于推进组织再生疗法至关重要.

研究的目的:

开发和描述混合PRP的 hialuronic acid (HA) 的冷解配方,以提高生物活性成分的稳定性和延长释放时间.
评估储存期间这些新型HA/PRP配方的生物活性,包括纤维细胞增殖,迁移和生长因子释放.

主要方法:

PRP的冷化与低至中等分子量 hialuronic 酸 (56 或 200 kDa) 结合.
生物物理和生物特征,包括初级人类皮肤纤维细胞增殖试验,划伤试验和ELISA用于生长因子释放 (PDGF-BB,VEGF).
在4°C和25°C保存6个月后,评估原蛋白和弹性蛋白的基因/蛋白质表达和*in vitro*伤口愈合疗效.

主要成果:

所有HA/PRP配方都增强了纤维细胞的增殖,并且与单独的PRP相比,显示出更高的伤口关闭率,24小时内80%的伤口关闭.
软化HA/PRP配方支持原蛋白和弹性蛋白的表达,并显示出改善的*in vitro*伤口愈合效果,长达3个月.
在4°C的存储允许延长保质期,而在25°C的存储导致3个月后有效性降低;长时间的存储需要非常低的温度 (-20°C) 来保存PRP的特性.

结论:

新型冷化HA/PRP配方代表了有前途的现成产品,可用于局部和皮肤内应用,特别是用于伤口愈合.
氨酸作为生物聚合物,促进PRP生长因子的缓慢释放,并在受控的寒冷条件下 (4°C) 延长保质期.
需要进一步研究最佳储存条件,以最大限度地提高这些再生生物材料的长期疗效.

Formation of the Platelet Plug

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Phases of Wound Repair

Phases of Wound Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

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...
