Lacun.3 Mouse Lung Adenocarcinoma Cell Line

Recent cancer research often studies a newly characterized type of cell referred to as cancer stem cells (CSCs) or also sometimes termed tumor-initiating cells (TICs.) These cells appear to have significant capabilities to grow, differentiate, generate tumors and resist chemotherapy. Tumor sphere cultures (TSCs) have emerged as a new format of studying cancer as well as understanding CSCs. The spheroid structures of TSCs appear to induce stem-like characteristics evidenced by the increased expression of stem cell markers. This 3D spheroid structure is also a much more accurate way to mimic the behavior of a solid tumor which develops in 3-dimensions and behaves quite differently from a monolayer cell culture. Spheroids are understood to have more tumor-forming capabilities when compared to monolayer cultures, yet the underlying mechanism for these characteristics is still under study. Stem-cell like properties, such as increased aldehyde dehydrogenase activity (ALDH), have already been used to identify CSCs in a variety of cancer types.

Lacun.3 cells are capable of forming spheroids that can be maintained over multiple passages and display increased cancer stem cell characteristics including increased ALDH activity.

Lacun.3 cells should be stored in liquid nitrogen. The cells can be cultured for at least 10 passages without significantly affecting cell marker expression and function.
