Research specialization (Major scientific fields of interest):
I. Keratinocyte (adult epidermal stem cell) Cell Biology:
(a) Isolation and setup of primary human Keratinocyte (adult epidermal stem cell) culture for application in burn’s patients for the wound closure.
(b) In vitro cultured human epidermis sheets were evaluated and confirmed by light & transmission electron microscopy and immunohistochemistry before grafting to the burn’s patients.
(c) Human and mouse dermal fibroblasts culture and its attenuation with Mitomycin C & further use for supporting the growth of human differentiated Keratinocyte.
II. Mycoplasma in Cell Cultures:
(a) Screening of adult epidermal stem cells (keratinocytes) for any micro-organisms including mycoplasma contamination by various detection methods before autologous grafting of epidermal sheets to the burn’s patients for wound closure.
(b) Detection & identification of mycoplasma contamination in routinely used cell cultures.
(c) Study the toxic effects and application of different anti-mycoplasma agents and antibiotics to eradicate mycoplasma contamination from cell cultures.
III. Pigment Cell Research:
(a) Isolation and setup of primary melanocytes culture from foreskin.
(b) Low level laser (red, blue & UV) irradiation to melanocytes for enhancing their growth & melanogenesis.
(c) Treatment of melanocytes with various plant extracts for enhancing their growth & melanogenesis.
IV. Cancer Biology: Low level laser (red, blue & UV) irradiation to SK-MEL-28 melanoma cancer cell line for reducing their growth for treatment of melanoma cancer.
V. Stem Cell Research: Low level laser (red, blue & UV) irradiation to Adipose-derived Stem cells and human embryonic stem cells derived mesenchymal stem cells for enhancing their growth & their use in regenerative medicine.
Technical skills: Animal cell culture techniques, sub-culturing, cryo-preservation, cell lines maintenance, MTT assay, cell migration assay, invasion assay, detection of mycoplasma contamination in cell lines, PCR, gel electrophoresis (horizontal & vertical), gel-doc imaging system, immunoflorescnce assay, immunohistochemistry, sample processing for transmission electron microscopy, animal handling, treatment of various cell lines with low-level lasers and anti-cancer agents, Quantitative Real-time PCR, western blot, quantification of melanin content from melanocytes.
