A 3D‑scaffold of PLLA induces the morphological differentiation and migration of primary astrocytes and promotes the production of extracellular vesi…
2019
The present study analyzed the ability of primary rat astrocytes to colonize a porous scaffold, mimicking the reticular structure of the brain parenchyma extracellular matrix, as well as their ability to grow, survive and differentiate on the scaffold. Scaffolds were prepared using poly-L-lactic acid (PLLA) via thermally-induced phase separation. Firstly, the present study studied the effects of scaffold morphology on the growth of astrocytes, evaluating their capability to colonize. Specifically, two different morphologies were tested, which were obtained by changing the polymer concentration in the starting solution. The structures were characterized by scanning electron microscopy, and a…
Analysis of MSCs' secretome and EVs cargo: Evaluation of functions and applications
2022
Mesenchymal stem cells (MSCs) can exert different functions and can be used in several medical fields. In the last years, MSC properties have been attributed to their secreted factors such as soluble proteins, cytokines and growth factors. Moreover, a key role is played by the extracellular vesicles (EVs) which lead a heterogeneous cargo of proteins, lipids and small and long non-coding RNAs that interfere with the pathways of the recipient cells. Due to the safeness and easiness in obtaining the secretome, its use is becoming a turning point for the application in physiological and pathological fields. This review summarizes the most recent studies on the use of MSCs secretome, focusing on…
