2013-287 – Researchers at Mayo Clinic have generated immortalized osteocytes derived from sclerostin (Sost-/-) knock out and wild-type (Sost+/+) mice. Clonal populations of cells were immortalized with SV40 T-antigen-containing viral constructs and maintained on collagen coated plates. Clone 8 (derived from Sost knock out mice) and clone 12 (derived from Sost wild-type mice) expressed mRNAs for... Read More
2013-273 – Background: Aerobic fitness is one of the best predictors of all-cause mortality but not easily assessed on a large scale accurately. Technology Description: A web based health fitness assessment tool which may be carried out at any location and requires nothing more than a device camera, web portal, a step, and a chair. Using technology based light reflection and color spectrum, heart... Read More
2013-102 – The Hdac3 conditional knockout mouse model made with Osx-Cre is a useful tool to study the molecular and physiological mechanisms by which factors (e.g., OPG and others) produced in the skeleton, particularly by immature osteoblasts and osteoblast progenitor cells, influence energy metabolism and prevent diseases like type 2 diabetes.
2012-188 – This invention is about using ultrasound for assessment of infant bone, and especially for evaluation of immature infants, who are at risk for osteopenia or other infant bone diseases. This method uses a ultrasound to generate a vibration in the bone and by analyzing the signal resulting from this vibration bone quality is evaluated.
2011-226 – The segmental loss of peripheral nerve may result from open or closed extremity trauma, resection of benign or malignant primary nerve tumors, or limb-sparing tumor surgery. Currently available reconstructive options include vascularized and conventional (nonvascularised) nerve autografts, nerve conduits from a variety of materials, nerve allografts and nerve transfer. Of these, autografting... Read More
2005-318 – Mayo Clinic Researchers have created a positively charged hydrogel for controlled DNA delivery for cell transplantation. Oligo- (polyethylene glycol) fumarate (OPF) hydrogel was copolymerized with 2-(methacryloyloxy) ethyl-trimethylammonium chloride (MAETAC) to produce a positively charged hydrogel. This hydrogel can be crosslinked with multiple systems and fabricated into sheets, sponges,... Read More
Hydrophilic/hydrophobic Hybrid Polymer Networks Based on Poly(caprolactone fumarate) (PCLF), Poly(Ethylene Glycol Fumarate) (PEGF), and PEGF-co-PCLF
2005-077 – We have developed a new route to synthesize the biodegradeable and injectable polymer poly(ethylene glycol fumarate) (PEGF) and its copolymer with Poly (caprolactone fumarate) (PCLF), PEGF-co-PCLF. These materials can be crosslinked with other unsaturated polymers via redox- or photo-initiation to form hybrid polymer networks. Characteristics of these hybrid networks, such as... Read More
2005-021 – Injectable, biodegradable oligo(poly(ethylene glycol) fumarate) (OPF) hydrogels were made from photopolymerization of OPF macromer with UV light and photoinitiator. Hydrogels with varying mechanical property and water content can be made with the change in macromer and crosslinking agent concentration in precursor solution. The biodegradable OPF hydrogels can be injected as fluid into the... Read More
2004-258 – Mayo Clinic Researchers have developed a new synthetic, biodegradable, injectable polymer, poly (epsilon-caprolactone fumarate) that is also photocrosslinkable. This new material is colorless or light-colored, and is shown to be self-crosslinkable by both redox initiation and photoinitiation. The molecular weight, chain flexibility, crystallinity, degradation rate, and mechanical properties... Read More
2004-200 – Mayo Clinic Researchers have developed a new synthetic, biodegradable, injectable polymer, poly (propylene fumarate-co-caprolactone) [P(PF-co-CL)]. This new material is a block copolymer of poly (propylene fumarate) (PPF) and poly (epsilon caprolactone) (PCL). The molecular weight, mechanical strength, chain flexibility, degradation rate, and crystallinity can be controlled by varying the... Read More
1995-155 – HFOBER cells are hFOBs stably transfected with human estrogen receptor; subclones HFOB/ER-3 and HFOB/ER-4 express levels of estrogen receptor consistent with the range of levels measured in human osteoblasts. The HFOBER cell lines have a complete concatenation of transcription factors such that the estrogen receptor is transactionally active; estrogen-regulated functions are maintained. The... Read More
1995-072 – A marker for detecting breast cancer and implications for pancreatic cancer. The novel TGFß/estrogen inducible gene (TIEG) has been identified in normal human fetal osteoblasts using differential-display PCR. TIEG is regulated by TGFß and estrogen in breast tissue, osteoblasts and other cell and tissue types. Thus in addition to being an interesting target for gene discovery, TIEG is a useful... Read More
1993-010 – Conditionally Immortalized Human Osteoblastic Cell Line: Normal human bone cells were stably transfected with a gene encoding a temperature-sensitive mutant (tsA58) of SV40 large T antigen; cells proliferate as if immortalized at 33.5C degrees but differentiate at 39.5C degrees; hFOB cells show normal bone cell characteristics with regard to responses to dihydroxyvitamin D3 and PTH, BMP’s,...
