Of the 19,000 bone and tissue fragments taken from the site, Dr. Shaler explains, more than half were so damaged that they did not yield usable DNA results.
Despite worries about decomposition, the Swiss team's report, which was obtained by al-Jazeera and shared with the Guardian prior to publication, found the bone and tissue fragments from the corpse showed "unexpectedly high" levels of radioactive polonium-210.
Current biopsy techniques acquire cytology samples and tissue biopsies, or even cytological sample with tissue fragments.
The biological constructs containing BMC/BMMSCs and articular tissue fragments were examined in vitro.
Furthermore, aspiration of the tissue fragments by the HM ensures a clear view and tissue is preserved for histological examination.
The tissue fragments were immediately frozen in liquid nitrogen at the time of surgery and stored at −80°C.

The SRC model was a generous gift from Dr. P.A. Guerne (Switzerland) as tissue fragments, which were frozen until use.
Scanning electron microscopic images revealed the cells in the constructs with BMC grew and attached into tissue fragments well.
The size of the tissue fragments was increased 1 2 fold compared with that before transplanted, and most tissue fragments were white in color.
After the washing, the tissue fragments were processed as described below.
