BACKGROUND

Due to many uses of cell culture in cell biology, biotechnology, and medical research, this technique has evolved into a widely used and accepted methodology. The isolation of primary cells from primary cancer tissue is a crucial step in cell culture technology since it offers a trustworthy source for studying the biology, morphology, and molecular evaluation of cancer cells, just like in the oral cavity tissue of patients. Therefore, the technique used for the isolation, culture, and evaluation of these cells is crucial.

AIM

The aim of the present study is to isolate and culture the cells from human primary Oral Squamous Cell Carcinoma [OSCC] tissue and evaluate them for morphological variations using an explant method.

MATERIALS AND METHODS

The patients with OSCC who were undergoing surgery provided the tissue samples. An explant technique was used to achieve the isolation of cells from tissue samples. Following that, the cells were maintained, subcultured, and stored in accordance with the standard American Type Culture Collection [ATCC] protocol. Routine Hematoxylin & Eosin and crystal violet stains were used. These cells were morphologically studied, and the results were assessed for further studies.

RESULTS

We were able to successfully isolate and culture cells from 4 different tissue samples using the explant method. Morphological analysis revealed that one tissue had a significantly distinct presentation of epithelial and stromal cells, whereas the other three tissues had only minor morphological differences predominantly stromal cells. Two tissues were discarded after showing contamination.

CONCLUSION

Tissue culture should be done very meticulously specially when oral cavity tissue is used as it is house for millions of microorganisms. The technique must also be thoroughly followed and adjusted accordingly. Using common, inexpensive stains like Hematoxylin and Eosin and crystal violet, which are of great help for examining the morphology of cells routinely.
