A highly safe procedure for the preparation of purified stem cell fractions of lipid origin is herein described, in which the use of a specially designed single collecting device, reduces the number of passages and manipulations undergone by stem cell-containing material, reducing to a minimum the risks of contamination, material loss, and inadvertent exchange of samples, and further simplifying the interface and cooperation between personnel recovering the raw material and those expert in stem cell isolation.

In recent years, there has been a shift toward tissue-engineering strategies using stem cells for plastic and reconstructive surgical procedures. Therefore, it is important to develop safe and reproducible protocols for the extraction of adipose-derived stromal cells (ASCs) to allow cells to be stored in liquid nitrogen for future needs. The aspirated liposuction obtained from healthy donors were immediately processed after the suction using a protocol developed in our laboratory. The resulting stromal vascular fraction (SVF) was then characterized by the presence of adipose-derived stromal cells, at later stage frozen in liquid nitrogen. After that, cells were thawed and again characterized by adipose-derived stromal cells, cellular survival, differentiation ability and Colony Forming Unit-Fibroblast like colonies (CFU-F). Extraction and freezing of cells contained in the stromal vascular fraction demonstrate that thawed cells maintain the full capability to grow and differentiate in culture. The advent of adipose-derived stromal cells use in tissue engineering will assume a wide role in esthetic restoration in plastic surgery. It is thus important to develop clinically translatable protocols for the preparation and storage of adipose-derived stromal cells. Our results show that adipose-derived stromal cells in serum free can easily be frozen and stored in liquid nitrogen with retention of 85% of cell viability and 180,890 cell/g yield plus normal proliferative capacity and differentiation potential compared with fresh controls. These observations set the basis for adipose-derived stromal cells banking. © 2014 The Authors. Source

The 2010 edition of the Lugano StemCellMeeting, under the auspices of the Swiss center of excellence in cardiovascular diseases " Cardiocentro Ticino" and the Swiss Stem Cell Foundation, offered an update on clinical, translational, and biotechnological advances in regenerative science and medicine pertinent to cardiovascular applications. Highlights from the international forum ranged from innate mechanisms of heart repair, safety, and efficacy of ongoing and completed clinical trials, novel generations of stem cellbiologics, bioengineered platforms, and regulatory processes. In the emerging era of regenerative medicine, accelerating the critical path from discovery to product development will require integrated multidisciplinary teams to ensure timely translation of new knowledge into validated algorithms for practice adoption.© Springer Science+Business Media, LLC 2010.

Multipotent mesenchymal stromal cells (MSCs) are a type of adult stem cells that can be easily isolated from various tissues and expanded in vitro. Many reports on their pluripotency and possible clinical applications have raised hopes and interest in MSCs. In an attempt to unify the terminology and the criteria to label a cell as MSC, in 2006 the International Society for Cellular Therapy (ISCT) proposed a standard set of rules to define the identity of these cells. However, MSCs are still extracted from different tissues, by diverse isolation protocols, are cultured and expanded in different media and conditions. All these variables may have profound effects on the selection of cell types and the composition of heterogeneous subpopulations, on the selective expansion of specific cell populations with totally different potentials and ergo, on the long-term fate of the cells upon in vitro culture. Therefore, specific molecular and cellular markers that identify MSCs subsets as well as standardization of expansion protocols for these cells are urgently needed. Here, we briefly discuss new useful markers and recent data supporting the rapidly emerging concept that many different types of progenitor cells are found in close association with blood vessels. This knowledge may promote the necessary technical improvements required to reduce variability and promote higher efficacy and safety when isolating and expanding these cells for therapeutic use. In the light of the discussed data, particularly the identification of new markers, and advances in the understanding of fundamental MSC biology, we also suggest a revision of the 2006 ISCT criteria. © Springer Science+Business Media, LLC 2011.
