How is Cord Blood Collected and Stored
                     How is Cord Blood 
Collected and 
Stored?
STEM CELL  CORD BLOOD BANKING
History of Cord blood Banking
 The science of bio-preservation 
spells out techniques like 
hypothermic storage, 
cryopreservation and vitrification in 
a clinical environment. The new 
market report on “Umbilical Cord 
Blood Banking Market,” released by 
Persistence Market Research on 
September 12, 2014, states that 
there would be an exponential 
demand for cell banking by 2020, 
owing to the multiple cord tissue 
banking benefits and 
stem cell banking benefits. 
 This has rightly pushed the bio-
preservation market to expand and 
gain much needed recognition.
What is Umbilical Cord Blood Banking?
 This technique involves the 
storage and collection of a 
newborn’s cord blood and 
tissue, for preserving it with 
continuous reliability over a 
long period of time.
  Need for this arose as a result 
of the immense potential 
linked to cord blood cells and 
numerous cord tissue banking 
benefits, in short, translating 
to the hope of regenerating 
damaged and infected organs, 
cells and tissues.
How is Cord Blood and Tissue Collected?
 Cord blood is extracted 
immediately after birth, using a 
quick and painless procedure. 
After the umbilical cord is cut, 
the blood is drawn out from the 
cord using a needle and a 
special collection bag. 
 The tissue in the cord lining is 
also extracted for preservation 
as an extension of the 
cord blood collection process. It 
is done by cutting a segment of 
the umbilical cord, after which 
it is stored in a sterile 
container.
How are the Collected Samples Processed?
 This refers to the process of 
separating the stem cells from 
the cord blood, so as to produce a 
sample that can be safely stored 
and used in clinical procedures.
  Even the United States Food and 
Drug Administration (FDA) urges 
that the cord blood unit should be 
reduced to a stage where there is 
low plasma and red blood cells, 
prior to cryopreservation. This will 
reduce the chances of future 
complications and fully promote 
the linked cord tissue banking 
benefits.
Patented Technology Linked to the 
Collection of Cord Blood
Many cord blood banks 
have strategically 
partnered with research 
institutes to use patented 
technology during cord 
blood extraction. 
CellOptima™ is one such 
proven technology that 
safely enables the 
extraction of cord 
blood cells and tissues.
Storage of Cells and Tissue
 After the samples have 
been collected and 
processed, the unit is ready 
for cryopreservation. No 
matter how the sample unit 
has been processed, a 
cryopreservant is added to 
it to ensure that the cells 
are able to survive through 
the cryogenic process. 
 The unit of cells is cooled 
slowly to a temperature of 
-90°C, after which it is 
transferred to a liquid 
nitrogen tank, to be kept 
frozen at -196°C. The slow 
cooling process is 
important so that all the 
cell and cord tissue banking 
benefits can be extracted 
at a later date.
