Suitability of a progenitor cell‐enriching device for in vitro applications

Abstract

Rigenera® is a novel class‐1 medical device that produces micro‐grafts enriched of progenitors cells without ex vivo manipulation of donor tissues. The manufacturer’s protocol has been supported for a wide variety of clinical uses in the field of regenerative medicine. This study aimed to evaluate its potential use for in vitro cell models. Human primary oral fibroblasts were cultured under standard conditions and processed through Rigenera® over a time course of up to 5 min. Cell viability was assessed using a Trypan Blue exclusion test. It is possible to process fibroblasts through Rigenera® although an initial reduction of cell viability was observed. Additionally, debris was evident in t..
