About this trial
The goal of this clinical trial is to evaluate if autologous mesenchymal stem cell (HUNS001-01) transplantation therapy can provide neurological recovery in patients with chronic stage of stroke resulting in moderate to severe neurological sequelae. The main questions it aims to answer are:
Can HUNS001-01 intracerebral transplantation demonstrate improvement in the mRS of disability for 1 year after intervention? Can HUNS001-01 intracerebral transplantation can be performed without any adverse events for 1 year after intervention?
Participants will receive the below interventions.
* Screening for the eligibility to enroll the clinical trial (interview, blood test, imaging) * Harvest of platelet concentrates (PC) * Harvest of bone marrows (BM) * Receive intracerebral transplantation surgery of HUNS001-01 * Post-operative rehabilitation * Follow-up studies (until 1 year or termination of the trial)
