It is a tool similar to a camera to allow for inspection of skin lesions unobstructed by skin surface reflections. The dermatoscope consists of a magnifier, a light source (polarized or non-polarized), a transparent plate and sometimes a liquid medium between the instrument and the skin. The dermatoscope is often handheld, although there are ...
Some skin products might increase comedones by blocking pores, [2] and greasy hair products (such as pomades) can worsen acne. [3] Skin products that claim to not clog pores may be labeled noncomedogenic or nonacnegenic. [6] Make-up and skin products that are oil-free and water-based may be less likely to cause acne. [6]
This stops the cells during mitosis, while the chromosomes are still visible. Once the cells are centrifuged and placed in a hypotonic solution, they swell, spreading the chromosomes. After preparation, the chromosomes of the cells can be viewed under a microscope to have the banding patterns of the chromosomes examined.
Basal-cell carcinoma (BCC), also known as basal-cell cancer, basalioma [7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it . [ 1 ]
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. [1] Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because ...
A live-cell microscope. Live-cell microscopes are generally inverted. To keep cells alive during observation, the microscopes are commonly enclosed in a micro cell incubator (the transparent box). Live-cell imaging is the study of living cells using time-lapse microscopy.
Keratoacanthoma is commonly found on sun-exposed skin, often face, forearms and hands. [2] [3] It is rarely found at a mucocutaneous junction or on mucous membranes. [2] Keratoacanthoma may be difficult to distinguish visually from a skin cancer. [4] Under the microscope, keratoacanthoma very closely resembles squamous cell carcinoma. In order ...
Scratch wound healing assay experiment of rhabdomyosarcoma, a cancer cell line. A wound healing assay is a laboratory technique used to study cell migration and cell–cell interaction. This is also called a scratch assay because it is done by making a scratch on a cell monolayer and capturing images at regular intervals by time lapse ...
