Chemical Shift Images of Organelles in Leydig cells of Mice Testes

Soft X-ray transmission images of Leydig cells of mice testes changing incident wavelength were observed with the use of a contact microscope. After normalization of transmission images, absorbance images were obtained and compared with a visible differential interference image. Some organelles were identified by the image comparison, and absorption spectra of the organelles were obtained from the absorbance images. The absorption spectra show that peak structures are different depending on the observed organelles. The structures and the positions of organelles were clearly identified at C-K absorption.
