O presente protocolo descreve como usar óleo vermelho O para tingir gotículas lipídicas (DLs), calcular o tamanho e o número de DLs em um modelo de hepatócitos gordurosos induzidos por ácidos graxos e usar BODIPY 493/503 para observar o processo de fusão de pequenas LDs em grandes LDs por imagem de células vivas.

Nossa pesquisa se concentra no número de gotículas lipídicas e no tamanho induzido pelo ácido linoleico em células hepáticas. Além disso, pretendemos fornecer informações sobre o mecanismo do fígado gorduroso. Avanços recentes neste campo de pesquisa, sugerem que colina, CCT alfa, estabelecida autofagia induzida, pode regular o tamanho de gotículas lipídicas em células hepáticas bovinas.

Além disso, observações em estações de trabalho de células vivas mostraram que os fosfolipídios têm um efeito considerável na fusão de gotículas lipídicas. Atualmente, auxílio gênico, fluorescência, cromatografia líquida, análise ômica, cromatografia única, citometria de fluxo e outras tecnologias estão sendo usadas para agrupar a vasta pesquisa neste campo. O método experimental apresenta algumas limitações.
