概括

与传统离心法相比,洗和过显著改善了脂填结果,增强了脂肪体积的维持和脂肪衍生的干细胞生长.

科学领域:

再生医学是一种再生医学.
组织工程是组织工程.
脂肪酸衍生干细胞生物学

背景情况:

机械操纵脂肪组织对于脂填成功至关重要,影响干细胞产量和脂肪移植的存活率.
之前的方法,如离心,对脂肪衍生干细胞 (ASC) 和脂肪体积维护有不同的影响.

研究的目的:

通过联合洗和过来净化脂肪填充来评估脂肪体积的维持.
在体外 (in vitro) 检查不同管血管分量 (SVF) 提取技术的ASC产量和生长能力.

主要方法:

一项前性病例控制研究,涉及20名为软组织缺陷而接受脂填治疗的患者.
患者被分为两组:洗/过 (研究) 和离心 (控制,科尔曼技术).
6个月后通过临床成像和MRI评估体积维持;SVF细胞在体外分析ASC产量和生长.

主要成果:

在6个月内,洗/过组的脂肪容量维持显著更高 (69%±5.0%),相比对照组 (44%±5.5%).
虽然ASC产量在统计上没有差异 (p=0.1805),但研究小组在体外表现出优异的细胞生长 (倍增6758 ± 0.7122与3888 ± 0.3078,p < 0.05).

结论:

洗和过代表了一个比离心更有效的系统来制备脂填充.
这种方法既提高了脂肪体积的维持,也提高了ASCs在树皮血管部分的增长潜力.

Cells Coordinate Growth and Proliferation

Cells Coordinate Growth and Proliferation

Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Liver Regeneration

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...
