Title in Portuguese
"Comparação de dois métodos de obtenção celular para cultura primária de queratinócitos bucais humanos"
Keywords in Portuguese
Cultura primária de células
Queratinócitos
Técnicas de cultura celular
Abstract in Portuguese
Freqüentemente as condutas terapêuticas utilizadas no tratamento de patologias bucais são cirúrgicas, resultando em falhas de continuidade da mucosa bucal. A possibilidade de obtenção de epitélios transplantáveis, a partir do cultivo in vitro de células da mucosa bucal, abre novas perspectivas de utilização, não se restringindo somente ao seu local de origem, ou seja, a boca, mas também como material de reconstrução para outras regiões, tais como: uretra, córnea, superfície ocular e epitélio córneo-limbal. Os métodos utilizados para a obtenção dessas células ainda são controversos na literatura. Neste sentido, avaliamos e comparamos a eficiência de dois métodos, enzimático e explante, para a obtenção de queratinócitos de mucosa bucal humana. Os fragmentos utilizados para a obtenção dessas células foram obtidos durante procedimentos cirúrgicos de pacientes voluntários saudáveis. Os queratinócitos foram cultivados sobre uma camada de sustentação, feeder-layer, confeccionada com fibroblastos murinos irradiados (3T3 - Swiss albino). Neste estudo foram comparados: o tempo para a obtenção dos queratinócitos, o rendimento obtido entre os dois métodos, a duração da vida útil em cultura, a capacidade que estas células tiveram em formar um epitélio in vitro e a morfologia dos mesmos. Os resultados obtidos, na avaliação dos dois métodos, comprovaram a possibilidade de obtenção dos queratinócitos, a partir de um pequeno fragmento bucal, porém pode-se verificar que existem vantagens e restrições peculiares a cada um dos métodos estudados.

The comparison of two methods to obtain human oral keratinocytes in primary culture

Keratinocytes
Primary cell culture
Abstract in English
The therapeutic procedures frequently used in oral treatments for the pathological diseases are surgical, resulting in failures of the mucosal continuity.The possibility to obtain transplantable oral epithelia from an in vitro cell culture opens new utilization perspectives not only to where it comes from, but also as a reconstructive matherial for other parts of the human body, such as: urethra, epithelia corneo-limbal, cornea, ocular surface. Many researchers still use controversial methods for obtaining cells. It was therefore evaluated and compared the efficiency in both methods: enzimatic and direct explant to obtain oral keratinocytes from human oral mucosa. Fragments of intra oral epithelial tissues from healthy human subjects, undergoing dental surgeries, were donated to the research project. The keratinocytes were cultivated over a feeder-layer from a previously irradiated 3T3 Swiss albino fibroblasts. In this study it was compared the time needed in the cell obtaintion, the best cell amount between both methods, the life-span, the cell capacity to form an in vitro epithelia and its morphologic structure. The results in the accessment of both methods have shown the possibility to obtain keratinocytes from a small oral fragment, but at the same time we may verify the advantages and peculiar restrictions for each one of both analyzed methods.
