The present invention provides a method for controlling the proliferation and differentiation of cord blood-derived hematopoietic stem cells with excellent safety when proliferating them by culturing. The airfoil is coupled to an active element that responds to signals from height control circuitry. Blood may be sampled from the user via the blood sampling device while the user has the finger against the fingerprint-reading panel. The sensor signal denotes the identifier. Endpoint security agents, security scanners, and remediation engines that carry out the foregoing functions reside on each of the quarantined and non-quarantined networks on hosts that are different from the target hosts. The opening exposes the recess of the first plug, the second plug and the sidewall of the bit line structure.
