血小板豊富なプラズマ (PRP) 療法は,慢性的な傷の治癒を大幅に改善し,患者の64%が80%以上の領域の縮小を示しました. 自体脂肪移植はさらなる利益をもたらさなかったので,PRPは
科学分野:
- 再生医療
- 傷 の 癒し
- 細胞療法
背景:
- 慢性的な傷は 重要な臨床的および医療上の課題を 引き起こします
- 感染症や血流不良などの要因を考慮して,多学科的な管理が不可欠です.
- 脂肪組織に由来する幹細胞 (ADSCs) と血小板に富んだ血 (PRP) は,傷の修復に有望である.
研究 の 目的:
- 慢性創傷治癒における血小板豊富な血 (PRP) と自己組織脂肪移植の有効性を評価する.
- 従来の治療に反応しない患者の傷面縮小と治癒時間を評価する.
主な方法:
- 31人の慢性創傷患者を対象とした前向きな観察研究です.
- PRPの浸透と/または自己脂肪の移植に続く標準的な脱皮.
- 傷の治癒は,臨床的および写真による評価によって監視され,傷面の縮小が主なアウトカムでした.
主要な成果:
- すべての患者は血小板濃縮プラズマ (PRP) 治療を受け,5人はPRPと脂肪移植を併用した.
- 64%の患者は> 80%の傷面縮小を達成し,平均49日で48. 3%が完全に治りました.
- 静脈不全,糖尿病,動脈不全が主な原因で,下肢の病変が最も一般的であった (84%).
結論:
- 血小板豊富なプラズマ (PRP) 治療は,慢性的な傷に対する安全で効果的な,適応可能な治療法です.
- PRPと併用された場合,自体の脂肪組織移転は追加の利益を示さなかった.
- PRP治療は,標準的な慢性創傷治療プロトコルに含まれる可能性を示しています.

01:19Overview of Regeneration and Repair
4.2K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
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...

01:28Phases of Wound Repair
6.3K
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.

01:21Stem Cell Therapy for Tissue Regeneration
4.2K
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.
