Copious cytoplasmic RER and shed external lamina and fibronectin.

<p><b>A</b>) The slightly tangentially sectioned cell has about equal RER and actin (A) with dense bodies (long red arrows). There is a single large primary lysosome (*), shed external lamina (short red arrows), and relatively sparse dense plaques (short black arrows). Case 13, original magnification 5,000×. <b>B</b>) A MF with more RER than peripheral actin (A)/dense bodies (long red arrows). The nucleus is large and irregular with a prominent nucleolus and apparently lost some chromatin during processing. Shed external lamina (short red arrow) and fibronectin (long black arrow) are prominent. Case 13, original magnification 4,000×.
