Article
Inadequate supplies of donor corneas have evoked an escalating interest in corneal xenotransplantation. However, innate immune responses contribute significantly to the mechanism of xenograft rejection. We hypothesized that complement component C5 and TLR co-receptor CD14 inhibition would inhibit porcine cornea induced innate immune responses. Ther...

This study aimed to investigate how prolonged storage of adult retinal pigment epithelial (ARPE-19) cell sheets affects cell metabolism, morphology, viability, and phenotype. ARPE-19 cell sheets were stored at three temperatures (4 ◦C, 16 ◦C, and 37 ◦C) for three weeks. Metabolic status and morphology of the cells were monitored by sampling medium...

Transplantation of cultured oral mucosal epithelial cells (OMECs) is a promising treatment strategy for limbal stem cell deficiency. In order to improve the culture method, we investigated the effects of four culture media and tissue harvesting sites on explant attachment, growth, and phenotype of OMECs cultured from Sprague-Dawley rats. Neither ch...

To assess the effect of storage temperature on the viability, phenotype, metabolism, and morphology of cultured human oral keratinocytes (HOK). Cultured HOK cells were stored in HEPES- and sodium bicarbonate-buffered Minimum Essential Medium (MEM) at nine temperatures in approximately 4°C increments from 4°C to 37°C for seven days. Cells were chara...

Gelatin based adhesives have been used in the last decades in different biomedical applications due to the excellent biocompatibility, easy processability, transparency, non-toxicity, and reasonable mechanical properties to mimic the extracellular matrix (ECM). Gelatin adhesives can be easily tuned to gain different viscoelastic and mechanical prop...

Objective In a recent study, we found an elevated level of interleukin 8 (IL-8) in response to bacterial incubation in thrombin-sufficient human whole blood anticoagulated by the fibrin polymerization blocking peptide GPRP. Whether thrombin directly activated leukocytes or mediated the release via thrombin-dependent activation of platelets remains...

Nanomedicine is seen as a potential central player in the delivery of personalized medicine. Biocompatibility issues of nanoparticles have largely been resolved over the past decade. Despite their tremendous progress, less than 1% of applied nanosystems can hit their intended target location, such as a solid tumor, and this remains an obstacle to t...

Electron beam (E‐beam) irradiation is an attractive and efficient method for sterilizing clinically implantable medical devices made of natural and/or synthetic materials such as poly(methyl methacrylate) (PMMA). As ionizing irradiation can affect the physicochemical properties of PMMA, understanding the consequences of E‐beam sterilization on the...

Purpose: To evaluate titanium (Ti) sputtering of the poly(methyl methacrylate) (PMMA) stem of the Boston Keratoprosthesis (BK) as a method to enhance interfacial adhesion between the PMMA and the recipient corneal tissue. Methods: PMMA specimens were plasma treated with Ar/O2 and coated with Ti using a DC magnetron sputtering instrument. The top...
Article
Innate immune activation has been attributed a key role in traumatic brain injury (TBI) and successive morbidity. In mild TBI, however, the extent and persistence of innate immune activation are unknown. We aimed to determine plasma cytokine level (1) changes over 12-months after a mild TBI in hospitalized and non-hospitalized patients compared to...
Article
To address the shortcomings associated with corneal transplants, substantial efforts have been focused on developing new modalities such as xenotransplantion. Xenogeneic corneas are anatomically and biomechanically similar to the human cornea, yet their applications require prior decellularization to remove the antigenic components to avoid rejecti...
Article
Purpose We fabricated and investigated polymeric scaffolds that can substitute for the conjunctival extracellular matrix to provide a substrate for autologous expansion of human conjunctival goblet cells in culture. Methods We fabricated two hydrogels and two silk films: (1) recombinant human collagen (RHC) hydrogel, (2) recombinant human collagen...
Article
The purpose of this study was to investigate the changes that occur in the lacrimal glands (LGs) in female thrombospondin 1 knockout (TSP1−/−) mice, a mouse model of the autoimmune disease Sjogren's syndrome. The LGs of 4, 12, and 24 week-old female TSP1−/− and C57BL/6J (wild type, WT) mice were used. qPCR was performed to measure cytokine expressi...

Purpose: Storage of cultured human oral keratinocytes (HOK) allows for transportation of cultured transplants to eye clinics worldwide. In a previous study, one-week storage of cultured HOK was found to be superior with regard to viability and morphology at 12°C compared to 4°C and 37°C. To understand more of how storage temperature affects cell p...

Purpose: Cultured oral mucosal epithelial cells can treat stem cell deficiency of the cornea. The present study aims to determine the best site for harvesting oral mucosal cells and the effects of four media on these cultured cells. Methods: Pieces of oral epithelium were used from four locations: buccal mucosa (BM), hard palate (HP), lower lip (LL...

To develop a one-week storage method, without serum and xenobiotics, that would maintain cell viability, morphology, and phenotype of cultured human limbal epithelial sheets. Human limbal explants were cultured on intact human amniotic membranes for two weeks. The sheets were stored in a hermetically sealed container at 23°C in either a serum-free...

Purpose: To evaluate the effect of storage temperature on the morphology, viability, cell number and metabolism of cultured human conjunctival epithelial cells (HCjEs). Materials and methods: Three-day cultured HCjEs were stored at nine different temperatures between 4 °C and 37 °C for four and seven days. Phenotype was assessed by immunofluores...

Diabetes is associated with microcirculatory dysfunction and heart failure and changes in insulin and IGF1 levels. Whether human cardiac microvascular endothelial cells (HMVEC-Cs) are sensitive to insulin and/or IGF1 is not known. We studied the role of insulin receptors (IRs) and IGF1 receptors (IGF1Rs) in metabolic, mitogenic and anti-inflammator...

Question
I have bought this primary cell line from ABM Goods. After culturing in T-25 ECM coated flask I have observed many dead and floating cells in the culturing vessel. Is this normal? Does anybody have similar experiences?
Question
I have placed order to a distributer of ScienCell for Human Oral Keratinocyte more then six months ago but haven´t got yet! They seem to be out of stock. I have some cells from ABM but I still need some other supplier.
Question
In the dot plot the dead cell population is distributed in the upper left and upper right quadrant. What does it mean when the cells population cloud is extended from the upper right to upper left quadrant?

The main research goal is to elucidate the role of complement as a primary inducer of the inflammatory reaction and thereby form a basis for a future therapeutic approach in complement-mediated disease processes. In particular the crosstalk between complement and the co-receptor CD14 of the Toll-like receptor (TLR) family is in focus. Further on to investigate the effect on inflammation by inhibiting complement activation and CD14 using human whole blood in vitro models and in vivo animal models of various human diseases.
