Analysis of MSCs' secretome and EVs cargo: Evaluation of functions and applications
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…
Spheroids of adipose derived stem cells show their potential in differentiating towards the angiogenic lineage
Introduction: Adipose derived stem cells (ASCs) are a mesenchymal stem cell population of great scientific interest due to their abundance and easiness in obtaining them from adipose tissue. Recently, several techniques for three dimensional (3D) ASCs cultivation have been developed to obtain spheroids of adipose stem cells (SASCs). It was already proved that ASCs are able to differentiate towards the endothelial lineage thus, for the first time, we investigated the ability of our 3D SASCs to differentiate endothelially and the effects of not differentiated SASC secreted factors on specific cultured cells. Materials and methods: SASCs were differentiated with a specific medium towards endot…
Systematic review on spheroids from adipose‐derived stem cells: Spontaneous or artefact state?
Three-dimensional (3D) cell cultures represent the spontaneous state of stem cells with specific gene and protein molecular expression that are more alike the in vivo condition. In vitro two-dimensional (2D) cell adhesion cultures are still commonly employed for various cellular studies such as movement, proliferation and differentiation phenomena; this procedure is standardized and amply used in laboratories, however their representing the original tissue has recently been subject to questioning. Cell cultures in 2D require a support/substrate (flasks, multiwells, etc.) and use of fetal bovine serum as an adjuvant that stimulates adhesion that most likely leads to cellular aging. A 3D envi…
