Don W. Fawcett (2011) CIL:10904, Cavia porcellus, sperm. CIL. Dataset

This electron micrograph shows the P-face of a small region of membrane from the midpiece of guinea pig sperm. The changing distribution of intramembranous particles (IMPs)in this image provided some of the first evidence of local variation in the organization of the membrane. Linear arrays of IMPs in the lower region of the micrograph are closely associated with mitochondria. This image first appeared in Fawcett, International Cell Biology 1976-7, p 588-600, Rockefeller University Press, New York, and was reprinted with permission as Figure 6 from Chapter 1 (The Cell Surface) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of the accompanying chapter is available on the ASCB's BioEDUCATE website.

本电子显微镜图像展示了来自豚鼠精子中段膜的小区域的P面。该图像中膜内颗粒（IMPs）分布的变化，为膜组织局部变异的第一手证据提供了部分内容。显微镜下方的线性IMPs阵列与线粒体紧密相关。该图像首次发表于Fawcett所著《国际细胞生物学》1976-7年第588-600页，由洛克菲勒大学出版社纽约出版，并经许可作为《细胞》第2版第一章（细胞表面）的图6重新印刷。相关章节的PDF副本可在ASCB的BioEDUCATE网站上获取。
