Eficacia de los factores de crecimiento derivados de plaquetas en el tratamiento de las lesiones condrales y osteocondrales
Effectiveness of platelet-derived growth factors in the treatment of chondral and osteochondral injuries

Rev. Asoc. Méd. Argent; 137 (2), 2024
Las lesiones condrales y osteondrales afectan a sectores del cartílago articular. Producen dolor, inflamación e impotencia funcional que evolucionan a osteoartritis. Los factores de crecimiento presentes en el plasma rico en plaquetas (PRP) son señales bioquímicas capaces de modificar las respuestas ...

Larger Chondral Lesions Treated with Collagen Membrane - Matrix-Induced Autologous Chondrogenesis - Show Larger Increase in Clinical Scores

Abstract Objective To evaluate clinically and radiologically the results of the treatment of chondral lesions using collagen membrane - autologous matrix-induced chondrogenesis (AMIC). Methods This is a series of observational cases, in which 15 patients undergoing AMIC were analyzed. The clinical eval...

Surgical treatment of chondral knee defects using a collagen membrane - autologus matrix-induced chondrogenesis

ABSTRACT Objectives: To evaluate the clinical and functional results of patients diagnosed with full-thickness chondral defects on symptomatic knees who underwent a biological repair technique using autologous matrix-induced chondrogenesis. Methods: Seven patients who underwent surgical treatment due t...

Micromass cultures are effective for differentiation of human amniotic fluid stem cells into chondrocytes

Clinics; 73 (), 2018
OBJECTIVES: Articular cartilage is vulnerable to injuries and undergoes an irreversible degenerative process. The use of amniotic fluid mesenchymal stromal stem cells for the reconstruction of articular cartilage is a promising therapeutic alternative. The aim of this study was to investigate the chondro...

Goat umbilical cord cells are permissive to small ruminant lentivirus infection in vitro

Braz. j. microbiol; 48 (1), 2017
Abstract Small ruminant lentiviruses isolated from peripheral blood leukocytes and target organs can be propagated in vitro in fibroblasts derived from goat synovial membrane cells. These cells are obtained from tissues collected from embryos or fetuses and are necessary for the establishment of the fibr...

PDK2 promotes chondrogenic differentiation of mesenchymal stem cells by upregulation of Sox6 and activation of JNK/MAPK/ERK pathway

Braz. j. med. biol. res; 50 (2), 2017
This study was undertaken to clarify the role and mechanism of pyruvate dehydrogenase kinase isoform 2 (PDK2) in chondrogenic differentiation of mesenchymal stem cells (MSCs). MSCs were isolated from femurs and tibias of Sprague-Dawley rats, weighing 300-400 g (5 females and 5 males). Overexpression and ...

Potential for in vitro mesoderm differentiation of Wharton's jelly cells from ovine umbilical cord isolated in different culture media

Pesqui. vet. bras; 36 (supl.1), 2016
The mammalian Wharton's jelly of umbilical cord (WJUC) is a promising source of multipotent cells, providing advantages due to ethical implications, ease of collection and the absence of teratomas in pre-clinical trials. Ovine multipotent cells have already been isolated from various tissues, however the...

Using mesenchymal stem cells as a therapy for bone regeneration and repairing

Biol. Res; 48 (), 2015
Bone is a unique tissue which could regenerate completely after injury rather than heal itself with a scar. Compared with other tissues the difference is that, during bone repairing and regeneration, after the inflammatory phase the mesenchymal stem cells (MSCs) are recruited to the injury site and diffe...

Biocompatibilidad de células madres mesenquimales de tejido gingival humano en cultivoconun andamiaje de polímero sintético de ácido poliláctico (OPLA)

Int. j. morphol; 32 (3), 2014
La ingeniería tisular se plantea como tratamiento ideal para la regeneración de tejidos con la utilización de andamiajes, células madres y factores de crecimiento. Las células madres de origen gingival plantean ventajas de obtención, mientras que el OPLA 3D permite cultivos de alta densidad celular...

Immunohistochemical study of amelogenin and lysosome-associate membrane proteins (LAMPs) in cartilage

Int. j. morphol; 32 (2), 2014
Amelogenin is one of the enamel matrix proteins secreted by ameloblasts during enamel formation in tooth development. Recent studies showed that the amelogenin is expressed in chondrocyte. Lysosome-associated membrane proteins (LAMPs) have been identified as binding partner proteins to amelogenin and it ...
