Fabrication and Performance Evaluation of Gelatin/Sodium Alginate Hydrogel-Based Macrophage and MSC Cell-Encapsulated Paracrine System with Potential Application in Wound Healing. Int J Mol Sci 2023; 24:ijms24021240. [PMID: 36674754 PMCID: PMC9867201 DOI: 10.3390/ijms24021240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 01/05/2023] [Accepted: 01/05/2023] [Indexed: 01/11/2023] Open
Abstract
A gelatin/sodium alginate-based hydrogel microsphere has been fabricated after reaction condition optimization. Macrophages (RAW246.7) and adipose mesenchymal stem cells (ADSC) have been subsequently encapsulated in the microsphere in order to construct a 3D paracrine system for wound healing treatment. The synthesized microsphere displayed neglectable cytotoxicity toward both encapsulated cells until 10 days of incubation, indicating promising biocompatibility of the microsphere. A qRT-PCR and ELISA experiment revealed positive regulation of cytokines (Arg-1, IL-6, IL-8, IL-10, bFGF, HGF, VEGF, TLR-1, and CXCL13) expression regarding macrophage phenotype transformation and anti-inflammatory performance both inside the microsphere and in the microenvironment of established in vitro inflammatory model. Additionally, positive tendency of cytokine expression benefit wound healing was more pronounced in a fabricated 3D paracrine system than that of a 2D paracrine system. Furthermore, the 3D paracrine system exhibited more efficiently in the wound healing rate compared to the 2D paracrine system in an in vitro model. These results suggested the current paracrine system could be potentially used as a robust wound healing dressing.

Abstract
As opposed to remarkable advances in the cell therapy industry, researches reveal inexplicable difficulties associated with preserving and post-thawing cell death. Post cryopreservation apoptosis is a common occurrence that has attracted the attention of scientists to use apoptosis inhibitors. Transporting cells without compromising their survival and function is crucial for any experimental cell-based therapy. Preservation of cells allows the safe transportation of cells between distances and improves quality control testing in clinical and research applications. The vitality of transported cells is used to evaluate the efficacy of transportation strategies. For many decades, the conventional global methods of cell transfer were not only expensive but also challenging and had adverse effects. The first determination of some projects is optimizing cell survival after cryopreservation. The new generation of cryopreservation science wishes to find appropriate and alternative methods for cell transportation to ship viable cells at an ambient temperature without dry ice or in media-filled flasks. The diversity of cell therapies demands new cell shipping methodologies and cryoprotectants. In this review, we tried to summarize novel improved cryopreservation methods and alternatives to cryopreservation with safe and viable cell shipping at ambient temperature, including dry preservation, hypothermic preservation, gel-based methods, encapsulation methods, fibrin microbeads, and osmolyte solution compositions.

Abstract
Induction of autophagy is a prospective approach to the treatment of neurodegeneration. In the recent decade, trehalose attracted special attention. It is an autophagy inducer with negligible adverse effects and is approved for use in humans according to FDA requirements. Trehalose has a therapeutic effect in various experimental models of diseases. This glucose disaccharide with a flexible α-1-1'-glycosidic bond has unique properties: induction of mTOR-independent autophagy (with kinase AMPK as the main target) and a chaperone-like effect on proteins imparting them natural spatial structure. Thus, it can reduce the accumulation of neurotoxic aberrant/misfolded proteins. Trehalose has an anti-inflammatory effect and inhibits detrimental oxidative stress partially owing to the enhancement of endogenous antioxidant defense represented by the Nrf2 protein. The disaccharide activates lysosome and autophagosome biogenesis pathways through the protein factors TFEB and FOXO1. Here we review various mechanisms of the neuroprotective action of trehalose and touch on the possibility of pleiotropic effects. Current knowledge about specific features of trehalose pharmacodynamics is discussed. The neuroprotective effects of trehalose in animal models of major neurodegenerative disorders such as Alzheimer's, Parkinson's, and Huntington's diseases are examined too. Attention is given to translational transition to clinical trials of this drug, especially oral and parenteral routes of administration. Besides, the possibility of enhancing the therapeutic benefit via a combination of mTOR-dependent and mTOR-independent autophagy inducers is analyzed. In general, trehalose appears to be a promising multitarget tool for the inhibition of experimental neurodegeneration and requires thorough investigation of its clinical capabilities.

Abstract
![]()
Tissue engineering
involves the transplantation of stem cell-laden
hydrogels as synthetic constructs to replace damaged tissues. However,
their time-consuming fabrication procedures are hurdles to widespread
application in clinics. Fortunately, similar to cell banking, synthetic
tissues could be cryopreserved for subsequent central distribution.
Here, we report the use of trehalose and gellan gum as biomacromolecules
to form a cryopreservable yet directly implantable hydrogel system
for adipose-derived stem cell (ADSC) delivery. Through a modified
cell encapsulation method and a preincubation step, adequate cryoprotection
was afforded at 0.75 M trehalose to the encapsulated ADSCs. At this
concentration, trehalose demonstrated lower propensity to induce apoptosis
than 10% DMSO, the current gold standard cryoprotectant. Moreover,
when cultured along with trehalose after thawing, the encapsulated
ADSCs retained their stem cell-like phenotype and osteogenic differentiation
capacity. Taken together, this study demonstrates the feasibility
of an “off-the-shelf” biomacromolecule-based synthetic
tissue to be applied in widespread tissue engineering applications.

Abstract
Background: Decellularized human nerves overcome the limitations of the current treatments for large peripheral nerve injuries. However, the use of decellularized nerves requires an "off-the-shelf" availability for useful and actual clinical application. In this study, we addressed the preservation of the native and decellularized human nerve matrix in an integrative approach for tissue scaffold production. Materials and Methods: For native nerve matrix preservation analysis, we used histological examination and immunofluorescence to examine the structure, biomechanical assays to evaluate the tensile strength and Young's modulus, and analyzed the extracellular matrix (ECM) composition using enzyme-linked immunosorbent assay (ELISA) and biochemical assays for laminin, collagen and sulfated glycosaminoglycans (sGAG). After decellularization, nuclear remnants and DNA content were evaluated using 4',6-diamidino-2-phenylindole (DAPI) staining and the picogreen quantification assay, as well as immunofluorescence or ELISA for cell rests (S100 protein and myelin staining) evaluation. Decellularized cryopreserved scaffolds were assayed for biomechanics, ECM composition, and structural maintenance. Cytotoxicity assays were performed to evaluate the biocompatibility of the nerve matrix extracts after cryopreservation. Results: We compared different strategies for native nerve storage and found that preservation up to 7 days at 4°C in Roswell Park Memorial Institute medium maintained biomechanical properties, such as Young's modulus and tensile strength, along with the structure and ECM composition, regarding laminin, collagen, and sGAG. After a successful decellularization process, that eliminated cell remnants, nerve scaffolds were frozen in an "in house" formulated cryoprotectant, using an automatic controlled rate freezer. Nerve structure, ECM composition, and biomechanical properties were maintained before and after the freezing process in comparison with native nerves. The extracts of the nerve scaffolds after thawing were not cytotoxic and the freezing process sustained good viability in 3T3 cells (graphical abstract). Conclusion: Since our approach facilitates transport, storage, and provide a ready-to-use alternative, it could be used in a clinical application for the treatment of long-gap peripheral nerve injuries in regenerative medicine.

Abstract
Cryoprotectants are crucial factors in cell cryopreservation. Trehalose (Tre), a nontoxic, nonreducing, and natural disaccharide, has the potential to protect cells as a cryoprotectant. As an inducer of autophagy, Tre can influence the development of many diseases and may also have an effect on cell cryopreservation through this mechanism. In this study, human aortic endothelial cells were preserved in different cryopreservation fluids with or without dimethyl sulfoxide and Tre was added. Subsequently, the expression of the main autophagy-related genes LC3, BECN, and P62, cell death and apoptosis, and the proliferation rate were measured in different groups after cryopreservation. Our data showed that Tre can improve the expression of the autophagy-related genes LC3 and BECN and reduce the expression of P62. Dead/alive staining and flow cytometry showed that cell death and cell apoptosis were reduced during cryopreservation with Tre. In addition, the cell proliferation rate after thawing was increased in the Tre group when compared with others. These results all indicated that there might be a connection between Tre-triggered autophagy and the protective role of Tre in cell cryopreservation. Furthermore, strategies to regulate autophagy to reduce apoptosis in this process should be investigated in future research.

Abstract
Trehalose, a naturally nontoxic disaccharide that does not exist in
mammals, stabilizes cell membrane integrity under oxidative stress
conditions, the mechanism of which is still unclear. Here, we analyzed the
effects of trehalose on sheep epididymis epithelial cell (EEC)
proliferation and its possible mechanisms. To study the effect of trehalose
on EECs, EECs were isolated from testes of 12-month-old sheep; cell counting kit-8 (CCK-8) was
used to measure the growth of the cells. Cell proliferation was evaluated by
assaying cell cycle and apoptosis, and RT-PCR was utilized to identify the
epididymal molecular markers glutathione peroxidase 5 (GPX5) and androgen receptor (AR). Next, reactive oxygen species (ROS)
content was evaluated by a dichloro-dihydro-fluorescein
diacetate (DCFH-DA) probe. Superoxide dismutase (SOD), catalase
(CAT), and glutathione peroxidase (GSH-Px) activities were evaluated by enzyme
chemistry methods, and GPX5 expression was evaluated by qRT-PCR and enzyme-linked immunosorbent assay (ELISA).
The results showed that 100 mM trehalose significantly improved the
proliferation potential of EECs, in which the cells could be serially
passaged 14 times with continued normal GPX5 and AR marker gene expression in vitro. The
trehalose can increase significantly a proportion of EECs in S phase
(P<0.01) and decrease significantly the apoptotic rate of EECs
(P<0.01) compared to the control. Moreover, the trehalose decreased
ROS significantly (P<0.01) and increased CAT
(P<0.01) and GSH-Px (P<0.05) activities significantly in EECs. GPX5 mRNA and
protein expression were also significantly upregulated in trehalose-treated
EECs (P<0.05 and P<0.01 respectively). Our study suggested
that exogenous trehalose exhibited antioxidant activity through increasing
the activities of CAT, GSH-Px, and the expression level of GPX5 and could be
employed to maintain vitality of sheep EECs during long-term in vitro culture.

Abstract
This work aimed at evaluating the potential of using natural deep eutectic systems (NADES) as cryoprotectant agents (CPAs). Several combinations between natural primary metabolites that have been identified in animals that live in extreme cold climates were prepared. All systems showed very little cytoxicity towards L929 cells at concentrations high as 1–2 M. Moreover, this cell line was highly tolerant to 10% (w/v) of NADES when compared to Me2SO. To test NADES as CPAs, two cell lines were used, L929 and HacaT cells. After freeze/thawing cycle, it was possible to observe that for L929 cells, NADES presented similar behaviour to Me2SO. For Hacat cell line a significant improvement on post-thawing recovery was observed. Moreover, the results presented herein showed that NADES do not need to be removed from the freezing media after thawing the cells, which is a great advantage of these materials. Additionally, we have shown that NADES can act as CPA when cells are frozen at −20 °C. In overall, the results demonstrate the high potential of NADES to be used in cryobiology as alternative CPAs.

Abstract
Cell cryopreservation is of vital significance both for transporting and storing cells before experimental/clinical use. Cryoprotectants (CPAs) are necessary additives in the preserving medium in cryopreservation, preventing cells from freeze-thaw injuries. Traditional organic solvents have been widely used in cell cryopreservation for decades. Given the obvious damage to cells due to their undesirable cytotoxicity and the burdensome post-thaw washing cycles before use, traditional CPAs are more and more likely to be replaced by modern ones with lower toxicity, less processing, and higher efficiency. As materials science thrives, nanomaterials are emerging to serve as potent vehicles for delivering nontoxic CPAs or inherent CPAs comparable to or even superior to conventional ones. This review will introduce some advanced nanomaterials (e.g., organic/inorganic nanoCPAs, nanodelivery systems) utilized for cell cryopreservation, providing broader insights into this developing field.

However, there are many problems and challenges in the conversion and clinical application of EVs. Storage and protection of EVs is one of the issues that need further research. To adapt to potential clinical applications, this type of problem must be solved. This review summarizes the storage practices of EVs in recent years, and explains the impact of temperature on the quality and stability of EVs during storage based on current research, and explains the potential mechanisms involved in this effect as much as possible.

Abstract
Cellular cryopreservation is a platform technology which underpins cell biology, biochemistry, biomaterials, diagnostics, and the cold chain for emerging cell-based therapies. This technique relies on effective methods for banking and shipping to avoid the need for continuous cell culture. The most common method to achieve cryopreservation is to use large volumes of organic solvent cryoprotective agents which can promote either a vitreous (ice free) phase or dehydrate and protect the cells. These methods are very successful but are not perfect: not all cell types can be cryopreserved and recovered, and the cells do not always retain their phenotype and function post-thaw. This Perspective will introduce polyampholytes as emerging macromolecular cryoprotective agents and demonstrate they have the potential to impact a range of fields from cell-based therapies to basic cell biology and may be able to improve, or replace, current solvent-based cryoprotective agents. Polyampholytes have been shown to be remarkable (mammalian cell) cryopreservation enhancers, but their mechanism of action is unclear, which may include membrane protection, solvent replacement, or a yet unknown protective mechanism, but it seems the modulation of ice growth (recrystallization) may only play a minor role in their function, unlike other macromolecular cryoprotectants. This Perspective will discuss their synthesis and summarize the state-of-the-art, including hypotheses of how they function, to introduce this exciting area of biomacromolecular science.

Abstract
In this study, three-dimensional (3D) hydrogels were used for human hepatocellular carcinoma (HepG2) cells culture systems in vitro and establishment of an in vivo xenografted tumor model. Based on our previous work on the biotin-conjugated pullulan acetate nanoparticles (Bio-PA NPs) as anticancer drug carriers, we further studied the anti-tumor effect of the NPs in two-dimensional (2D) and 3D cell culture system. When embedded in 3D hydrogels, HepG2 cells formed tumor spheroids and the cytoplasmic actin microfilamentrates were rearranged over a period of 7 days. In vitro cytotoxicity results indicated that HepG2 cells in 3D hydrogels were more resistant to Bio-PA NPs treatments compared to the 2D system. The tumor formation rate of in vivo xenografted tumor model using 3D culture systems method was 98.2%, which was significantly higher than that using of 2D cultured cells (76.4%). Then we injected the 3D HepG2 cells systems in the right anterior axillary of female Balb/c nude mice, and evaluate the in vivo anti-tumor efficacy of Bio-PA NPs. In summary, these results suggested that HepG2 cells in 3D hydrogel system has shown the potential to provide an in vitro and in vivo model and for the evaluation of Bio-PA NPs.

Abstract
Currently in the USA, one name is added to the organ transplant waiting list every 15 min. As this list grows rapidly, fewer than one-third of waiting patients can receive matched organs from donors. Unfortunately, many patients who require a transplant have to wait for long periods of time, and many of them die before receiving the desired organ. In the USA alone, over 100,000 patients are waiting for a kidney transplant. However, it is a problem that affects around 6% of the word population. Therefore, seeking alternative solutions to this problem is an urgent work. Here, we review the current promising regenerative technologies for kidney function replacement. Despite many approaches being applied in the different ways outlined in this work, obtaining an organ capable of performing complex functions such as osmoregulation, excretion or hormone synthesis is still a long-term goal. However, in the future, the efforts in these areas may eliminate the long waiting list for kidney transplants, providing a definitive solution for patients with end-stage renal disease.
