| 总结: | Among several requirements for the manufacture of Advanced Therapy Medicinal
Products (ATMP) are: following the guidelines of a pharmaceutical quality system, complying with
Good Manufacturing Practice (GMP) and access to a cleanroom fulfilling strict environmental
conditions (Class A work area and Class B environment). This makes ATMP expensive. Moreover,
the production of many of these therapeutic products may also be unprofitable, as in most cases
their use is limited to a few patients and to a single batch per manufacturing unit. To reduce costs,
ATMP may be produced in a scaled-down system isolated from the external environment (isolator),
allowing for placement of this facility in a Class D environment, which is much more permissive
and less costly. In this work, we confirm that it is possible to manufacture bioengineered corneal
epithelium inside an isolator while fulfilling all the safety assurance standards at an affordable cost
for patients. This small-scale ultra-clean working environment complies with GMP guidelines and
could be a solution for the high costs associated with conventional cleanroom ATMP production.
