From: The involvement of the nuclear lamina in human and rodent spermiogenesis: a systematic review
a Immunolocalisation of Lamin B1, LEMD1, BAF and BAF-L (green) on human spermatids and testicular spermatozoa. Labelling is shown on successive steps of spermiogenesis: round spermatid (RS), elongating spermatid (ES), testicular spermatozoa (TS). The acrosome is identified using lectin PNA (red) and DNA is counterstained with DAPI (blue). Scale bar is 10 μm. b Schematic representation of nuclear lamina proteins and nuclear partner proteins during human spermiogenesis. Successive steps are represented: round spermatid (RS), elongating spermatid (ES), testicular spermatozoa (TS). The acrosome is represented in green. LEMD1: LEM domain containing 1; LEMD2-Cter: LEM domain containing 2-Cterminal region; BAF: Barrier-to-Autointegration Factor; BAF-L: Barrier-to-Autointegration Factor Like; LAP2b: LAP2: lamina-associated polypeptide 2-β isoform
