Estudo das células Neuro2A sobre os biomateriais PCL e PLLA

Abstract: Resumo: Os biomateriais poli L-ácido lático (PLLA) e o poli caprolactona (PCL) são os polímeros mais estudadas na área dos materiais bioreabsorvíveis. Dentre as suas principais características que contribuem para a interação celular, temos a especificidade química da superfície, elétrica, hidrofobicidade e topografia. Ainda, observa-se o tempo de degradação, porosidade, biocompatibilidade com o tecido biológico, bem como, a confecção com as mais variadas formas e dimensões. Já a prática da cultura celular, tem… Show more

“…The data obtained can be seen in Table IV. According to the literature, the electrospinning parameters influence the structural morphology of the fibers, their variation is important for the optimization of fiber production [16]. These parameters are: solution flow, the potential difference that generates the electromagnetic field, the distance from the tip of the needle to the collection apparatus and the diameter of the needle [1,3], in addition to humidity, temperature and viscosity.…”

“…By contrast, biomaterials from synthetic origins allow better control of the desired characteristics, such as porosity, architecture, stiffness, and degradation rate [31]. Some of the most promising synthetic biomaterials are poly (L-lactic acid) (PLLA) and poly (ε-caprolactone) (PCL) [32]. PLLA is a thermoplastic product from starch, which is found in renewable resources such as potatoes, corn, and sugarcane [33].…”

“…Além de ser biocompatível, ele apresenta propriedades como biorreabsorção, devido às ligações éster que sofrem hidrólise quando em contato com os fluidos corpóreos. Os produtos resultantes deste processo são reabsorvidos pelo organismo, fazendo parte do metabolismo de carboidratos(49)(50)(51).…”
