Step by step about collection of umbilical cord tissue

When?

Umbilical cord tissue can be harvested immediately after drawing umbilical cord blood, usually before expulsion of the placenta, but even after its expulsion, too.

Who?

The umbilical cord can be harvested by the obstetrician or the midwife assisting the birth. The harvesting kit contains all necessary instruments.

How?

Harvesting of the umbilical cord shall also be done with the greatest possible care and under sterile circumstances – using a sterile harvesting kit, wearing sterile gloves and mask. This is possible both in the case of vaginal birth and of Caesarean section. The detached part of the umbilical cord will be placed in a sterile collecting glass, and after filling the glass up with physiological saline solution, it will be closed.

How much?

From the point of view of processing, the ideal length of the umbilical cord segment is 20 cm. If the length is lesser than 8 cm, we do not recommend the storage of the segment, because the number of stem cells that can be isolated from the umbilical cord tissue is too small.

Storage and transportation

During transportation to the laboratory, umbilical cord tissue should be kept on a temperature between 4 to 30 oC and protected from extreme temperature variations. The harvesting kit comprises the freezing bags needed for this purpose. These bags are equipped with a special data recording unit for temperature measurement, which allows the retrospective tracing of the conditions in which the sample has been transported and stored. We attach special importance to processing the sample sent to the laboratory within 36 hours from harvesting.
