The final stages of cell division is captured in the scanning electron micrograph. Two daughter cells are still interconnected by slender strands of membrane (white arrow at center of image). Lamellipodia extend from the periphery of each new cell as they begin to spread on the substrate, and microvilli stud the surface over the nucleus. The funnel-like cones (black arrows) are candidate sites for pinocytosis. Image contributed by Keith Porter first appeared in Porter and Bonneville, The Fine Structure of Cells and Tissues, Philadelphia: Lea and Febiger, 1973, and reprinted with permission as Figure 49 from Chapter 2 (Specializations of the Free 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.

细胞分裂的终末阶段在扫描电子显微镜下被清晰捕捉。两个子细胞仍由细长的膜状结构相连（图中中心白色箭头所指）。随着新细胞开始在基底上扩散，其外围延伸出薄片状突起，而微绒毛则覆盖在细胞核表面之上。黑色箭头所指的漏斗状锥体是可能的胞饮作用发生部位。该图像由Keith Porter提供，首次发表于Porter和Bonneville合著的《细胞与组织的精细结构》，费城：Lea和Febiger出版社，1973年出版，并经授权作为《细胞》第二版第二章（自由表面的专门化）中的图49。该章节的PDF副本可在ASCB的BioEDUCATE网站上获取。
