Abstract

Cryopreservation is commonly used for the storage of cells, tissues, organs or 3D cell-based products using ultra-low temperatures, which involves the immersion in liquid nitrogen for their long-term preservation. The cryopreservation of several microencapsulated cells is usually performed by the slow freezing with the dimethyl sulfoxide (DMSO) as a cryoprotectant agent (CPA). In this study, we cryopreserved several microencapsulated cells with the natural, non-toxic low molecular-weight hyaluronan (LMW-HA) at 5% and DMSO 10% solution assessing cell viability and metabolic activity after thawing. The cryopreservation of microencapsulated D1 mesenchymal stem cells (D1MSC) and murine myoblast cells (C2C12) with the LMW-HA 5% presented similar outcomes after thawing compared to the DMSO solution, showing the low molecular weight hyaluronan as a natural, non-toxic CPA that can be used preventing the DMSO related adverse effects after the implantation of the cryopreserved cell-based products.

Background

Cell microencapsulation is extensively used to enclose cells allowing the exchange of nutrients between the environment and the core of the microcapsule containing the cells. In vivo, microcapsules protect the cells from the immune system while allowing the release of therapeutic molecules by the entrapped cells (Orive et al., 2014). Consequently, these advantages have promoted the development and employment of cell encapsulation in organ replacement, tissue engineering and regenerative medicine as drug and cell delivery therapies (Gurruchaga et al., 2015b). Nowadays the storage of microencapsulated cells is performed by slow freezing using a linear cooling rate (-0.3-1 °C/min) (Murua et al., 2009). Different cryoprotectant agents (CPAs) have been used for their cryopreservation being dimethylsulfoxide (DMSO) the most used with good results in a wide range of microencapsulated cells (Massie et al., 2011; Gurruchaga et al., 2015a; Gryshkov et al., 2015). However, DMSO has been related to several adverse reactions after the implantation of cryopreserved cell-based products (Shu et al., 2014; Ruiz-Delgado et al., 2009) such as cardiac arrhythmia, cardiac arrest, tonic-clonic seizure or diarrhea among others, being other alternative CPAs investigated to overcome the DMSO’s drawback (Mantri et al., 2015). In this context, low molecular weight hyaluronan (LMW-HA), a natural non-toxic CPA, has demonstrated cryoprotective effects in the cryopreservation of several cell types (Hutson et al., 2009; Ujihira et al., 2010; Iwama et al., 2014). Therefore, in this study, we have determined the cryoprotective effect of LMW-HA 5% for the cryopreservation of D1 mesenchymal stem cells (D1MSC) and murine C2C12 myoblast (C2C12) compared to DMSO 10% in each cell medium. LMW-HA 5% preserved the metabolic activity and cells viability similarly to DMSO containing solutions after thawing, showing the potential of LMW-HA as a CPAs. Although the use of LMW-HA as a CPA has been investigated in microencapsulated cells, it may represent an alternative CPA in the cryopreservation of other 3D cell-based products avoiding the use of DMSO.
