July 17, 2019 - Characterization of an umbilical cord blood sourced product suitable for allogeneic applications
Aim: Umbilical cord blood (UCB) sourced allografts are promising interventions for tissue regeneration. As applications of these allografts and regulations governing them continue to evolve, we were prompted to identify parameters determining their quality, safety, and regenerative potential...read more
November 1, 2017 - A completely biological "off-the-shelf" arteriovenous graft that recellularizes in baboons
Prosthetic arteriovenous grafts (AVGs) conventionally used for hemodialysis are associated with inferior primary patency rates and increased risk of infection compared with autogenous vein grafts. We tissue-engineered an AVG grown from neonatal human dermal fibroblasts entrapped in bovine fibrin gel that is then decellularized...read more
June 2017 - Dendritic Cell (APC) and Autologous T-Cell Response (White Paper)
Xeno Diagnostics has added a mixed lymphocyte tumor cell assay to our list of services. The mixed lymphocyte tumor cell (MLTuC) is a method for generating T-lymphocytes that are cytotoxic to specific tumor cells. This assay offers a means to screen various pharmacological agents for their ability to enhance T-cell cytotoxicity to specific neoplasms. Click here to download.
2017 - Cells Isolated from Cadaveric Bone Marrow are Safe for Use in Bone Healing and Effective at Promoting Osteogenic Re-construction
The efficacy and immune-modulation of mesenchymal stem cells is well documented. The issue of obtaining mesenchymal stem cells without patient risk, extensive intra-operative procedure, cell manipulation or exposure of cells to harmful reagents remains an issue. This study was designed to test the viability, composition, and osteogenic potential of cells derived...read more.
December 7, 2016 - Xeno has won its 4th consecutive Laboratory Excellence Award following its most recent regulatory inspection.
Xeno Diagnostics has received an award for Laboratory Excellence following its most recent COLA inspection, making this the fourth consecutive inspection for Xeno to receive this award. Xeno has met all criteria for Laboratory Accreditation by COLA, a national healthcare accreditation organization. Accreditation is earned only by laboratories that apply rigid standards of quality in day-to-day operations, demonstrate continued accuracy in the performance of proficiency testing, and pass a rigorous on-site laboratory survey with no citations....read more
February 9, 2016 - Modfied glycan models of pig-to-human xenotransplantation do not enhance the human-anti-pig T cell response.
Genetically modified porcine models of pig-to-human xenotransplantation offer the most immediate answer to a growing shortage of available solid organs. Recently a modified porcine glycan model has been discovered that reduces human antibody binding to levels comparable with allograft standards. As this background provides an answer to the problem of acute humoral xenograft rejection (AHXR), it is important to consider the impact these modifications have on...read more
December 29, 2015 - Mechanism of Butyrate Stimulation of Tryglyceride Storage and Adipokine Expression during Adipogenic Differentiation of Porcine Stromovascular Cells
Short chain fatty acids (SCFA), products of microbial fermentation of dietary fiber, exert multiple metabolic effects in cells. Previously, we had demonstrated that soluble fiber influenced fat mass accumulation, gut microbial community structure and SCFA production in pigs...read more
August 2015 - Heat stress enhances adipogenic differentiation of subcutaneous fat depot - derived porcine stromovascular cells
Heat stress (HS) results from excessive heat load on animals such that all adaptive mechanisms used to dissipate the heat do not return the body to normal body temperature. In pigs, HS results in increased fat deposition compared with pair-fed animals in a thermoneutral environment...read more
March 22, 2015 - Full Length Single Chain, A Novel gp120-CD4 Fusion HIV Subunit Vaccine, Does Not Cause a Deleterious Autoimmune CD4 Response in Cynomolgus Macaques
Full length single chain (FLSC) is a novel HIV vaccine that presents conserved CD4i epitopes on HIV envelope. The constrained structure is achieved with single chain complexes of gp120 and CD4 fragments. FLSC elicits cross-reactive antibodies and heterologous protection against SHIV/SIV in three independent...read more
December 17, 2014 - Xeno Diagnostics Receives 3rd Award for Laboratory Excellence
Xeno Diagnostics has again received an award for Laboratory Excellence following its most recent COLA inspection. Xeno has met all criteria for Laboratory Accreditation by COLA, a national healthcare accreditation organization. Accreditation is earned only by laboratories that apply rigid standards of quality in day-to-day operations, demonstrate continued accuracy in the performance of proficiency testing, and pass a rigorous on-site laboratory survey...read more
September 10, 2014 - Xeno Diagnostics Adds Dr. Daniel Wierda as Director of Research and Development
Xeno Diagnostics, LLC, announced today that Dr. Daniel Wierda has joined Xeno as their new Director of Research and Development. Dan brings with him a great depth of experience in the area of immunotoxicology and cell-based assays. Prior to joining Xeno, Dan worked for 22 years at Eli Lilly and Company as a research scientist and toxicologist...read more
March 14, 2013 - Metabolic markets in Ossabaw pigs fed high fat diets enriched in regular or low a-linolenic acid soy oil
Soy oil is a major vegetable oil consumed in the US. A recently developed soybean variety produces oil with a lower concentration of a-linolenic acid, hence a higher (n-6)/(n-3) ratio, than regular soy oil. The study was conducted to determine the metabolic impact of the low a-linolenic acid containing soy oil...read more
