Quantitative Assessment of Extracellular Matrix Effect on A549 Attachment and Spreading
The Cell Index increases proportionately as the coating concentration of collagen IV increases. (Data and figures adapted from ACEA Biosciences, unpublished data).
Mammary Stem-Like Cells Have Increased Tubulin-Dependent Initial Reattachment From Suspension
(A) Stem-like HMLE cells attach at signifi cantly faster rates than non-stem-like HMLE cells as determined by electrical impedance expressed as Cell Index. Stem-like HMLE and non-stem-like cells both have significantly reduced attachment when treated with the microtubule polymerization inhibitor colchicine (50µM). For all reattachment assay: lines, mean for quadruplicate wells; bars, SD; representative graph from three independent experiments is shown. (B) Phase contrast images of HMLE non-stem-like (a-d) and stem-like (e-h) subpopulations reattaching from suspension. Panels, 10x magnification; Insets, 60x magnification (Data and figures adapted from Charpentier MS, et al., 2014).
