--Mark Hill 07:47, 29 March 2009 (EST) Thank you for your feedback. Lecture 4 - Cell Nucleus did not discuss cell adhesion, so I find you comment a little confusing. Have a look at the nucleus information again. Cell Export - Exocytosis I am glad you found the content easy to understand and to listen too. Yes, the unique nuclear lamin skeleton will be discussed in Cytoskeleton - Intermediate Filaments and Cell Division.
