  2. 1. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

    Author : Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; Finland Kuopio University of Kuopio Department of Anatomy; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

    Abstract : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. READ MORE

  4. 2. Development and optimization of a 3D in vitro model for osteogenic biomaterial evaluation

    Author : Luis Oliveros Anerillas; Peyman Kelk; Paul J. Kingham; Mikko Lammi; Jöns Hilborn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; angiogenesis; biomaterial; bone marrow mesenchymal stem cells; bone regeneration; hydrogel; osteoinduction; osteogenesis; scaffold; type I collagen; 3D culture; biology; biologi; biomedical laboratory science; biomedicinsk laboratorievetenskap; Medical Cell Biology; medicinsk cellbiologi;

    Abstract : Despite the innate regenerative capabilities of bone tissue, self-repair is impaired when an injury exceeds the critical size threshold because of trauma, congenital, or pathological conditions. Autologous transplantation is the gold standard to reconstruct large bone defects. READ MORE

  5. 3. Responses of fibroblasts and chondrosarcoma cells to mechanical and chemical stimuli

    Author : Juha Piltti; Mikko Lammi; Jukka Häyrinen; Frank Beier; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rho-kinase inhibition; Y-27632; hypoxia; cyclic stretching; human chondrosarcoma 2 8 cells; chondrocyte phenotype; fibroblasts; proteomics; protein pathway analytics; Medical Cell Biology; medicinsk cellbiologi;

    Abstract : Osteoarthritis is an inflammation-related disease that progressively destroys joint cartilage. This disease causes pain and stiffness of the joints, and at advanced stages, limitations to the movement or bending of injured joints. Therefore, it often restricts daily activities and the ability to work. READ MORE

  6. 4. Studies on various culture systems for chondrocytes and osteoblasts

    Author : Juha Prittinen; Mikko Lammi; Minna Kellomäki; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; chondrocyte; osteoarthritis; surface materials; topography; tissue engineering; mechanical stimulation; Medical Cell Biology; medicinsk cellbiologi;

    Abstract : Osteoarthritis and osteochondral defects are ailments that are increasing in frequency as the lifespan of the population increases and sedentary lifestyle becomes more common. Osteoarthritis is an inflammatory disease that causes the progressive degeneration of articular surfaces and the underlying bone. READ MORE

  7. 5. Articular cartilage proteoglycan biosynthesis and sulfation

    Author : Chengjuan Qu; Mikko Lammi; Heikki Helminen; Juha Töyräs; Anna-Marja Säämänen; Finland Kuopio University of Kuopio Anatomy Department of Biomedicine; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cartilage; Chondrocytes metabolism; Chondroitin sulfates; Glycosaminoglycans; Osteoarthritis; Proteoglycans; Glucosamine; Sulfation; Biochemistry; biokemi; cellforskning; cell research; Orthopaedics; ortopedi;

    Abstract : Glucosamine (GlcN) and glucosamine sulfate (GS) have been used to treat the patients with osteoarthritis(OA) as a disease-modifying agent. Previousin vitro studies have focused on the effects of GlcN or GSon cartilage metabolism, whereas in vivo studies have investigated their potential for the treatment of OA. READ MORE
