Contact us"The longitudinal CD34+ tracking report gave me information I could not have assembled from three separate clinic visits. The format was clear enough to include directly in the patient's hospital record."Dr. Kenji MurakamiHematologist, Tokyo Medical University Hospital
"I sent a sample from Osaka via the courier coordination service. It arrived, was processed, and I had a full report in my inbox within six business days. The methodology notes answered every question I had before I even thought to ask them."Dr. Kenji MurakamiInternal medicine specialist, Osaka
"I appreciated that the consultation was framed as an information session rather than a sales call. Dr. Kenji Murakami walked me through the published literature on my specific cell profile and was honest about what the evidence does and does not support."Takashi NishimuraIndividual client, Tokyo

A flow cytometry report lands on a desk and, for most people who are not hematologists, it reads like a decoded transmission from another discipline — columns of percentages, cryptic CD numbers, gates that look like abstract art. That gap matters clinically, because misreading a single value can push a patient toward an unnecessary biopsy or, worse, delay a referral that should have happened last week. This walkthrough takes a standard CD34+ report, the kind issued after a peripheral blood or bone marrow collection, and explains each major panel in plain language. The goal is not to replace specialist interpretation but to give patients and generalist physicians enough vocabulary to ask the right questions in the room. Stem Lab Zone's team reviewed anonymized report formats from multiple accredited South African hematology laboratories and found that the three panels causing the most confusion were CD34 enumeration, the lymphocyte scatter gate, and the viability readout — so those get the most space here.

"Dr. Kenji Murakami spent eight years as a research associate at the RIKEN Center for Biosystems Dynamics Research in Kobe before founding Stem Lab Zone in 2019. His doctoral work at Kyoto University focused on hematopoietic stem cell quiescence, and his post-doctoral research produced three peer-reviewed papers on CD34+ population dynamics in aging cohorts. He founded Stem Lab Zone after identifying a consistent gap between the granularity of laboratory data and the binary language used in clinical reports. His work has been cited in publications from the Japanese Society for Regenerative Medicine. Outside the laboratory, he keeps a detailed field notebook of the migratory bird populations in Tokyo Bay, a habit he says teaches him more about longitudinal observation than any statistics course."
No. Stem Lab Zone is an analysis and cryopreservation laboratory. We do not administer treatments of any kind. Our consultation service provides information about your cell profile and the published literature relevant to it. Any treatment decisions are made by your physician, not by us.
We coordinate temperature-controlled courier pickup through Yamato Transport's medical logistics division. Once you have a confirmed analysis plan from us, we arrange the pickup window, provide the correct transport container, and track the shipment from your location to our Minato-ku facility. Samples from Osaka, Nagoya, and Fukuoka typically arrive within 18 hours.
It is a composite score derived from flow cytometry and trypan blue exclusion, expressed on a 0-100 scale. A score of 100 would mean every cell in the sample is viable by both measures. We also provide your score's percentile position within our reference dataset of 1,400 samples, so you have context for what the number means relative to a real population.
