A Step-by-Step Guide to Your Stem Cell Therapy Day in Japan

8 min read

Hello, I am Dr. Hidenori Shimada of Grand Green Osaka Umekita Clinic in Osaka, Japan.

Medical travel to Japan is becoming an increasingly popular option for individuals seeking advanced healthcare, including innovative treatments like regenerative medicine. Adipose-derived stem cell therapy, which utilizes your body’s own cells, is one such area of interest. However, undergoing a medical procedure in another country can naturally come with questions and uncertainties, especially regarding the process on the day of treatment. This guide provides a clear, step-by-step overview of what to expect on the day of your adipose stem cell therapy at Grand Green Osaka Umekita Clinic, designed to help international patients feel informed and at ease.

What to Expect: The Outpatient Procedure in a Nutshell

Adipose-derived stem cell therapy is a process that involves collecting a small amount of your own fat tissue, isolating and culturing the mesenchymal stem cells (MSCs) within it at a specialized facility, and then administering these cells back into your body, typically through an intravenous (IV) infusion. The procedures on the day of fat collection and the day of infusion are both performed on an outpatient basis, meaning no hospital stay is required. The typical flow involves a consultation, a minor procedure for fat collection under local anesthesia, and later, a separate appointment for the IV infusion. While this is a general outline, the specific details of your treatment plan will be determined by a physician based on your individual health condition. A thorough consultation with a doctor is essential before proceeding with any treatment.

Addressing Common Concerns for International Patients

When considering treatment abroad, it’s normal to have questions. Many of our international patients share similar concerns before their visit. We aim to address these points to ensure you feel comfortable and well-prepared.

  • The Procedure Steps: What exactly happens from the moment I arrive at the clinic?
  • Discomfort and Anesthesia: What is involved in the fat collection process? Is it a major surgery?
  • Time Commitment: How long will I need to be at the clinic on the day of the procedure?
  • Recovery: What are the immediate post-procedure guidelines and restrictions?
  • Language and Communication: Will I be able to communicate effectively with the medical staff?

This article will walk you through the entire process, answering these questions to demystify your treatment day experience.

A Step-by-Step Guide to Your Treatment Day

The adipose stem cell therapy journey is divided into two main visits to the clinic: the day of fat collection and, after a few weeks of cell culturing, the day of IV infusion. Here’s a detailed look at what happens during each stage.

Visit 1: The Fat Collection Procedure

Step 1: Arrival and Final Consultation
Upon arriving at the clinic, you will have a final consultation with the physician. This is an opportunity to review your health status, confirm the details of the procedure, and ask any last-minute questions. You will also finalize the necessary consent forms.

Step 2: Fat Tissue Collection
This is a minor procedure performed under local anesthesia. The physician will make a very small incision, typically in the abdominal area, to collect a tiny amount of subcutaneous fat tissue—often just a few pieces the size of a grain of rice. Because only a small quantity is needed and local anesthesia is used, the physical burden is generally considered minimal. The collection process itself is usually completed in about 20-30 minutes.

Step 3: Post-Procedure Care and Departure
After the collection, the small incision is closed. You will be given instructions for at-home care. You can typically return to your daily activities shortly after, though strenuous exercise should be avoided for a period as advised by your doctor. This concludes your first visit.

The Interim Period: Cell Culturing

The collected fat tissue is sent to a specialized, licensed cell processing facility. There, mesenchymal stem cells are isolated, purified, and cultured over several weeks to multiply their numbers. This process is conducted under strict safety and quality controls as mandated by Japan’s Act on the Safety of Regenerative Medicine.

Visit 2: The IV Infusion Day

Step 4: Arrival and Preparation
A few weeks after the fat collection, you will return to the clinic for the administration of your cultured stem cells. After a brief check-up to ensure you are feeling well, you will be guided to a comfortable room for the infusion.

Step 5: IV Infusion
The cultured stem cells are administered back into your body through a standard intravenous (IV) drip. The process is similar to receiving any other IV treatment and typically takes about 30 to 60 minutes. During this time, you can relax comfortably.

Step 6: Post-Infusion Rest and Departure
Following the infusion, you will rest at the clinic for a short observation period. Once the medical staff confirms that you are well, you are free to leave. As with the collection day, this is an outpatient procedure, and you can return to your accommodation afterward.

Important Information Before Your Consultation

It is crucial for patients to have a clear understanding of the nature of this treatment. Adipose-derived stem cell therapy is provided as a private medical treatment and is not covered by Japanese public health insurance. The outcomes and responses can vary from person to person, and no results can be guaranteed. A physician’s consultation is necessary to determine if you are a suitable candidate for this therapy. During your consultation, the doctor will provide a detailed explanation of the expected benefits, as well as the potential risks and side effects. All treatments in Japan are provided under a plan submitted to and accepted by the Ministry of Health, Labour and Welfare, in compliance with the Act on the Safety of Regenerative Medicine.

Conclusion: A Clear Path for Your Treatment Journey

Embarking on a medical journey in a new country can feel daunting, but knowing what to expect can make a significant difference. The process for adipose-derived stem cell therapy is structured into clear, manageable steps, all conducted on an outpatient basis. From the initial fat collection to the final IV infusion, the focus is on patient comfort and safety. The most important step, however, is a thorough discussion with a qualified physician to understand if this treatment aligns with your personal health goals.
