  "account": "Proper cell alignment is essential for the functionality of tissues like skeletal muscle, neural cells, and adipose-derived stem cells. Existing in-vitro fabrication techniques, such as photolithography and 3D printing, are not cost-effective and fail to replicate the intricate surfaces these cells encounter. This study utilized bio-mimicked leaf templates to closely replicate the in-vivo environment for muscle cells and cultured C2C12 cells on modified PDMS substrates. Image analysis software was employed to examine cell alignment, aspect ratio, and cell area on these surfaces. C2C12 cells grown on PDMS substrates derived from the front and back sides of Musaceae Banana banana leaves exhibited the highest aspect ratios of 6.3 and 8.3, and the greatest degree of alignment. Similarly, cells cultured on the negative replica of Dracaena Sanderiana's back side showed the highest cell alignment. Given the vast array of leaf templates and bio-mimicked surfaces, identifying the optimal design remains challenging. Consequently, this research created a catalog of 15 different leaf surfaces, classifying them based on their groove patterns to offer a more extensive range of surface designs for studying cell behavior. Additionally, the study quantitatively analyzed groove patterns using 2D FFT analysis to determine the dominant groove wavelength. Surface hydrophobicity was also considered, with water contact angles measured for these surfaces. The findings underscore the significance of surface topography and hydrophobicity in affecting cell alignment, paving the way for the creation of biomimetic surfaces to advance tissue engineering applications.",
  "summary": "Proper alignment of cells is crucial for functioning of various tissues such as skeletal muscle tissues, neural cells, adipose-derived stem cells, etc. Current in-vitro fabrication methods to replicate the cellular environment, e.g., photolithography and 3D printing, are not cost-effective and cannot capture the complexity of the surfaces to which these cells are exposed to. In this work, we used…",
