Efficient and unbiased tools for quantitating Leydig and Sertoli cells in the testis from testes biopsies
Bente Pakkenberg, Peter M Petersen, Aleksander Giwercman, Hans J Gundersen
Izvirni znanstveni članek
Oznake:
The possibility of obtaining reliable estimates of the total number of Sertoliand Leydig cells from biopsies by use of the optical fractionator method was tested. The total number of Sertoli and Leydig cells was 522x106 (CV=0.27) and 89x106 (CV=0.34), respectively, when sampling in the entire testis ...

Stereological estimation of tubular length from thin vertical sections
Helle V. Clausen, Hans J.G. Gundersen, Lise G. Larsen
Izvirni znanstveni članek
Oznake:
In this study tubular structures are represented by stem villous arteries of the human placenta. The architecture of the vascular tree in the human placenta makes it appropriate to use vertical histological sections. Describing tubules, estimates of total length and diameter are informative. The aim ...

Evaluation of bone-to-implant contact and bone density adjacent to titanium implants using a stereological technique on ground sections
Dimitra Balatsouka, Klaus Gotfredsen, Hans Jørgen G. Gundersen
Izvirni znanstveni članek
Oznake:
When bone implants have to be examined in situ ground sections are required. Histomorphometric measurements are usually performed on two-dimensional sections, causing biased results when they are wrongly extrapolated to 3D without any knowledge of stereology. Unbiased results can only be obtained us ...

Stereology of neuronal connections (myelinated fibers of white matter and synapses of neocortex) in human brain
Yong Tang, Jens Randel Nyengaard, Bente Pakkenberg, Hans Jørgen G. Gundersen
Izvirni znanstveni članek
Oznake:
Unbiased stereological sampling and counting techniques for estimating the total length, total volume and diameter distribution of myelinated nerve fibers in white matter and the total number of synapses in neocortex of human autopsy brains were described. Uniform random sampling of tissues from ent ...
