“…Immobilized monosulfated HA facilitated the proliferation and TNAP activity of human osteoblasts in the same manner as a coating with collagen [97]. Implant coating with collagen fibrils and CS or CS-PGs promotes adhesion and differentiation of osteoblasts and osseointegration [87,[107][108][109][110][111][112].…”

“…The main influence of PGs is, unlike that of the glycoproteins, not based on the direct interaction with cell adhesion receptors, but rather with other cell surface receptors, and on their ability to bind growth factors and cytokines. Decorin and biglycan in a collagen matrix for instance are able to influence cell adhesion, as they accelerate and enhance the formation of focal adhesions in osteoblastic cells 3 , 20 . They also promote proliferation of human osteoblastic cells.…”

“…While on collagen TGFβ reduced cell proliferation and raised collagen synthesis, on collagen/biglycan there was a stronger reduction in proliferation and on collagen/decorin a stronger increase in collagen synthesis 20 . BMP-2 in combination with collagen and perlecan (the domain I fragment) supported chondrogenic differentiation in mouse embryonic mesenchymal cells 45 …”

“…Neste aspecto, um dos métodos que proporcionam evidência indireta da exposição de colágeno em uma superfície é o MEV/EDS, pela avaliação da detecção de S. Em estudo prévio do nosso grupo, empregando ácido cítrico a 50 % sobre superfície de osso fresco (REZENDE et al, 2015), a detecção de S aumentou significantemente com o tempo de desmineralização até 90 segundos, declinando aos 180 segundos, sugerindo que pode ter havido uma exposição gradual de moléculas contendo S, como colágeno tipo I, na superfície desmineralizada. Vários estudos confirmaram que moléculas sulfatadas como glicosaminoglicanas sulfatadas presentes na matriz óssea melhoram a adesão, proliferação e diferenciação de osteoblastos in vitro (DOUGLAS et al, 2007;DOUGLAS et al, 2008;BIERBAUM et al, 2006;NAGAHATA et al, 2004;NURCOMBE;COOL, 2007). Entretanto, neste estudo, a %A de S diminuiu significantemente após a desmineralização nos dois grupos teste, sem diferença significante entre eles e não foi encontrada base biológica para explicar esse evento, já que nos grupos desmineralizados houve melhor comportamento celular.…”
