Matrigel® as 3D culture medium: 2D vs. 3D changes in proliferation and ultrastructure
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 1
Abstract
3D cell culture has great potential in the field of tissue engineering and regenerative medicine. Three- dimensional ECM-like substances such as Matrigel® mimic natural proteins found in the ECM and result in a more accurate reflection of cell growth within the human body. In our lab, we compared HT1080 cells transfected with the histone H2B-green fluorescent protein (GFP) growing directly on glass (2D) to those in Matrigel® on the basis of cell growth, proliferation, division and morphology. During cell counting, the cells were maintained at a near-homeostatic temperature, humidity and CO2 level in a custom stage top environmental chamber [1] while being imaged on an Olympus (Melville, NY) IX70 inverted fluorescence microscope. Our results indicated that cell growth, division and proliferation were of greater magnitude in Matrigel® than on a glass coverslip (control). For ultrastructure imaging purposes, a culture of MDCK cells (Canis familiaris, kidney, normal) that were transfected with a pEYFP-Tubulin plasmid subcellular localization vector were used. Widefield epifluorescent analysis indicated that there was no significant difference in cellular ultrastructure on the basis of flat/rounded morphology and microtubule distribution between the cells grown in glass-bottomed Petri dishes and those in Matrigel®. These results are consistent with our hypothesis that cells in Matrigel® would exhibit greater cell growth, proliferation, and division while maintaining normal cell morphology.
