BACKGROUND: Rapid tissue expansion has been attempted, aiming at shortening the period of conventional expansion. However, it has scarcely been clinically applied because of its drawbacks such as low expansion efficiency and tissue destruction. Adipose-derived stem cell transplantation is a promising therapeutic method in regenerative medicine. However, its effects on rapid expansion remain poorly understood. METHODS: Twenty-four expanders were implanted in the dorsum of 12 pigs...

Articular cartilage defects are common, causing significant pain and morbidities. To date, tissue engineering techniques using adipose-derived mesenchymal stem cells have offered a promising modality for cartilage repair. In this study, we investigated the effects of Eucomis autumnalis (E. autumnalis) aqueous crude extracts in porcine adipose-derived mesenchymal stem cells (pADMSCs) to determine whether they can differentiate pADMSCs into chondrocytes. Porcine ADMSCs were prepared and treated with different concentrations of E...

Considerable progress has been made in the field of microfluidics to develop complex systems for modeling human skin and dermal wound healing processes. While microfluidic models have attempted to integrate multiple cell types and/or 3D culture systems, to date they have lacked some elements needed to fully represent dermal wound healing. This paper describes a cost-effective, multicellular microfluidic system that mimics the paracrine component of early inflammation close to normal wound healing. Collagen and Matrigel are tested as materials for coating and adhesion of dermal fibroblasts and human umbilical vein endothelial cells (HUVECs)...

BACKGROUND: Acute kidney injury (AKI) is an underestimated, yet important, risk factor for the development of chronic kidney disease (CKD). Persistence of inflammation after a renal ischemic injury has been observed, both in experimental models and patients, and is thought to be an important mechanisms underlying progression of acute-to-chronic renal injury. Temporary suppression of inflammation immediately after AKI might therefore be a good first-line therapeutic strategy towards a better long term outcome...

Lipoaspirates contain a readily accessible heterogeneous cell source for use in bone regeneration collectively referred to as the stromal vascular fraction (SVF). However, the osteogenic potential of SVF is inferior to other progenitor cell populations, thereby requiring alternative strategies to potentiate its effective use in cell-based therapies of bone repair. Cell-secreted extracellular matrix (ECM) is a promising substrate to guide cell phenotype or for use in biomaterial design, yet the instructional capacity of ECMs produced by various cell types is unknown...

Melanoma cell sensitivity to targeted therapy molecules is dependent on the tumor microenvironment (cell-cell and cell-extracellular matrix interactions). Three dimensional (3D) in vitro cell culture systems better reflect the native structural architecture of tissues and are attractive to investigate cellular interactions. We have developed and compared several metastatic melanoma models: melanoma cells (SK-MEL-28 and SK-MEL-3, BRAF V600E mutant and SK-MEL-2 BRAF wt) cultured as a monolayer (2D) and co-cultured on 3D dermal equivalents with fibroblasts to better unravel factors modulating cell sensitivity to a BRAF inhibitor (BRAFi, vemurafenib)...

Cells respond to both physical and chemical aspects of their substrate. Whether intracellular signals initiated by physical stimuli are fundamentally different from those elicited by chemical stimuli is an open question. Here we show that the requirement for a stiff substrate and therefore high cellular tension in order for cells to produce large focal adhesions and stress fibers is obviated when a soft substrate contains both hyaluronic acid (HA) and an integrin ligand (collagen I). HA is a major ECM component that is often upregulated during wound healing and tumor growth...

Facial skin aging is accelerated in postmenopausal females due to decreased collagen, reduced hydration, and loss of skin elasticity constituting the characteristics of estrogen deficient skin (EDS). The presence of estrogen receptors on dermal fibroblasts and epidermal keratinocytes confirms the role of estrogen in skin health. This research examined the efficacy and tolerability of topical methyl estradiolpropanoate (MEP) as an anti-aging cosmeceutical with estrogen like cutaneous effects in postmenopausal women who had never taken hormone replacement therapy (HRT)...

Murine herpesvirus-68 (MHV-68) productively infects mouse lungs, exhibiting a complex pathology characteristic of both acute viral infections and chronic respiratory diseases. We sought to discover proteins differentially expressed in bronchoalveolar lavage (BAL) from mice infected with MHV-68. Mice were infected intranasally with MHV-68. After nine days, as the lytic phase of infection resolved, differential BAL proteins were identified by two-dimensional (2D) electrophoresis and mass spectrometry. Of 23 unique proteins, acute phase proteins, vitamin A transport, and oxidative stress response factors Pdx6 and EC-SOD (Sod3) were enriched...

Abolished or delayed wound healing is a serious problem in clinical surgery, therefore, the new therapy for wound healing is needed. Synthetic oligodeoxynucleotides containing one or more CpG motifs (CpG ODN) has been reported to activate the immune system and improves skin wound healing. The aim of the present study was to evaluate the role of a new C-type CpG ODN in wound healing. We found that the CpG ODN promoted cell proliferation and collagen I production in human skin fibroblasts cells. Besides, we also investigated the effect of CpG ODN on the activation of immune cells...

Pathological features of pulmonary fibrosis include accumulation of myofibroblasts and increased extracellular matrix (ECM) deposition in lung tissue. Contractile α-smooth muscle actin (α-SMA)-expressing myofibroblasts that produce and secrete ECM are key effector cells of the disease and therefore represent a viable target for potential novel anti-fibrotic treatments. We used primary normal human lung fibroblasts (NHLF) in two novel high-throughput screening assays to discover molecules that inhibit or revert fibroblast-to-myofibroblast differentiation...

Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac matrix remodeling. A classic model of DCM was established in BALB/c mice by immunization with porcine cardiac myosin. Cardiac fibroblasts were isolated from neonatal Sprague-Dawley rats by density gradient centrifugation...
