Continuous Electrical Stimulation Affects Initial Growth and Proliferation of Adipose-Derived Stem Cells

2020

The aim of the study was to establish electrical stimulation parameters in order to improve cell growth and viability of human adipose-derived stem cells (hADSC) when compared to non-stimulated cells in vitro. hADSC were exposed to continuous electrical stimulation with 1.7 V AC/20 Hz. After 24, 72 h and 7 days, cell number, cellular surface coverage and cell proliferation were assessed. In addition, cell cycle analysis was carried out after 3 and 7 days. After 24 h, no significant alterations were observed for stimulated cells. At day 3, stimulated cells showed a 4.5-fold increase in cell numbers, a 2.7-fold increase in cellular surface coverage and a significantly increased proliferation.…

Non-adherent progenitors from Adipose-derived Stem Cells (napASCs): a new prospective for tissue engineering?

Adipose-derived stromal stem cells (ASCs) as a new regenerative immediate therapy combating coronavirus (COVID-19)-induced pneumonia.

2020

A coronavirus (HCoV-19) has caused the novel coronavirus disease (COVID-19) outbreak in Wuhan, China. Preventing and reversing the cytokine storm may be the key to save the patients with severe COVID-19 pneumonia. Mesenchymal stem cells (MSCs) have been shown to possess a comprehensive powerful immunomodulatory function. This study aims to investigate whether MSC transplantation improves the outcome of 7 enrolled patients with COVID-19 pneumonia in Beijing YouAn Hospital, China, from Jan 23, 2020 to Feb 16, 2020. The clinical outcomes, as well as changes of inflammatory and immune function levels and adverse effects of 7 enrolled patients were assessed for 14 days after MSC injection. MSCs …

Analysis of Immunomodulatory Properties of Spheroids from Adipose-derived Stem Cells

2020

Purpose: Adipose Stem Cells (ASCs) represent promising cell therapies for regenerative medicine and immunomodulation. The recently isolated spheroids from adipose-derived stem cells (S-ASCs) have shown being superior stemness and enhanced regenerative capability than the classical ASCs. The aims of this study were (1) to investigate the effects of adipose tissue donor-site, harvesting technique and patients’ characteristics on the yield of S-ASCs and (2) to investigate the immunomodulatory properties of S-ASCs comparing them with the adherent ASCs. Material and Methods: The study was divided into two phases. Phase I (prospective clinical study) between July 2016 and August 2019 was conducte…

INTRODUCING NON-ADHERENT PROGENITORS FROM ADIPOSE-DERIVED STEM CELLS (NAPADSCS): PROOF OF STEMNESS AND POSSIBLE FUTURE APPLICATIONS IN REGENERATIVE S…

2012

Introduction: Mesenchymal Stromal Cells (MSCs) can be isolated from adipose tissue and are currently used in vitro for experimental studies. MSCs are often mislabeled as Adipose-derived Stem Cells (ADSCs) despite presenting a more differentiated phenotype. The isolation and expansion of non-adherent progenitors from adipose-derived stem cells (napADSCs), has been achieved in our laboratory and is currently under investigation. In this study we investigate: a) the proof of stemness of such progenitors, and b) the feasibility of napADSCs adhesion over Integra® for cell colonization and for future differentiation and engineering of semi-synthetic tissues. Material and Methods: Adipose tissue (…

ADHESION AND OSTEOGENIC DIFFERENTIATION OF NON-ADHERENT PROGENITORS FROM ADIPOSE-DERIVED STEM CELLS (napASCs) OVER INTEGRA DERMAL REGENERATION TEMPLA…

2012

INTRODUCTION: Non-adherent progenitors from adipose-derived stem cells (n.a.p.ASCs) represent an upstream lineage of multipotent stem cell progenitors capable of clonal expansion and asymmetric divisions comparable to stem cell spheres observed in breast, thyroid and colon, and, as such, confirm the stemness of cells extracted from lipoaspirate. The identification of napASCs confirms the stem-cell origin of the more differentiated and commonly used adherent mesenchymal stromal cells (MSCs). NapASCs adhesion for differentiation purposes may be useful in tissue engineering. In this study we investigate the feasibility of napASCs adhesion over Integra® dermal regeneration template for cell col…

Skin Immunomodulation during Regeneration: Emerging New Targets

2021

Adipose-Derived Stem Cells (ADSC) are present within the hypodermis and are also expected to play a pivotal role in wound healing, immunomodulation, and rejuvenation activities. They orchestrate, through their exosome, the mechanisms associated to cell differentiation, proliferation, and cell migration by upregulating genes implicated in different functions including skin barrier, immunomodulation, cell proliferation, and epidermal regeneration. ADSCs directly interact with their microenvironment and specifically the immune cells, including macrophages and T and B cells, resulting in differential inflammatory and anti-inflammatory mechanisms impacting, in return, ADSCs microenvironment and …
