Cord Blood vs. Cord Tissue: Understanding the Differences
Cord blood and cord tissue are valuable sources of stem cells collected from the umbilical cord after childbirth. They serve different medical purposes and contain distinct types of stem cells:
-
Cord Blood: Contains hematopoietic stem cells (HSCs), used to treat over 80 blood-related diseases, including cancers, immune deficiencies, and metabolic disorders.
-
Cord Tissue: Rich in mesenchymal stem cells (MSCs), showing potential in regenerative medicine, such as tissue repair and autoimmune disease treatments.
Quick Comparison
| Feature | Cord Blood | Cord Tissue |
|---|---|---|
| Stem Cell Type | Hematopoietic (HSCs) | Mesenchymal (MSCs) |
| Primary Uses | Blood and immune disorders | Regenerative medicine |
| Treatment Status | FDA-approved for 80+ diseases | Experimental (300+ trials) |
| Collection Timing | After cord clamping | After cord blood collection |
| Storage Options | Public or private banks | Mostly private banks |
Storing both cord blood and cord tissue maximizes future treatment possibilities, combining proven therapies with emerging regenerative medicine applications. Let’s explore their differences, uses, and storage options in detail.
Cord Blood vs Cord Tissue Stem Cells
Cord Blood Basics
Cord blood contains hematopoietic stem cells (HSCs), which develop into the blood cells needed for immune and blood functions. Once discarded as medical waste, cord blood gained importance after a groundbreaking 1988 transplant saved Matthew Farrow's life [2].
Types of Stem Cells in Cord Blood
Cord blood is rich in hematopoietic stem cells (HSCs) that are used to treat blood disorders, immune system deficiencies, and certain cancers. These cells can transform into various blood cell types and have unique features, such as:
-
A higher concentration of natural killer cells
-
Fewer T-cells overall
-
A greater percentage of immature T-cells [1]
Next, let’s walk through how cord blood is collected and stored.
Cord Blood Collection and Storage Methods
Collection Stages and Key Details:
| Stage | Process | Key Notes |
|---|---|---|
| Collection Timing | After a 30–60 second clamping delay per ACOG guidelines | Requires coordination with the delivery team [7] |
| Collection Method | Blood is drawn from the umbilical cord into a special bag | The process takes just a few minutes [6] |
| Initial Processing | Disease screening | Ensures the collected blood is safe for use [3] |
| Storage Preparation | Cryogenic freezing for long-term preservation | Studies show viability can extend beyond two decades [6] |
Umbilical cord blood can be collected without risk to the mother or infant donor. [6]
If you're thinking about cord blood banking, it's best to decide before the 34th week of pregnancy [3]. Choosing between public and private banking depends on factors like family health history, costs (private banks charge collection and annual storage fees), and whether you want to donate to public health efforts.
Studies reveal that cord blood, when stored properly, can remain viable for many years [6], making it a long-term resource for family health.
Cord Tissue Basics
Cord tissue, also known as Wharton's Jelly, surrounds the umbilical blood vessels and contains stem cells with regenerative abilities that differ from the blood-forming cells found in cord blood [5].
Types of Stem Cells in Cord Tissue
Cord tissue is rich in mesenchymal stem cells (MSCs), known for their anti-inflammatory and regenerative properties, along with several other cell types:
| Stem Cell Type | Location | Potential Applications |
|---|---|---|
| Mesenchymal Stem Cells (MSCs) | Throughout cord tissue | Regeneration of bone, cartilage, muscle, and nerve tissues |
| Human Umbilical Vein Endothelial Cells (HUVECs) | Blood vessel lining | Engineering of vascular tissues |
| Epithelial Cord Lining Stem Cells (CLSCs) | Cord lining | Wound healing and organ repair |
| Human Umbilical Cord Perivascular Cells (HUCPVCs) | Around blood vessels | Bone growth and skin tissue engineering |
There are currently over 300 clinical trials focused on MSCs [8]. Let’s look at how cord tissue is collected and preserved to retain its regenerative potential.
Cord Tissue Collection and Storage Methods
Unlike cord blood, cord tissue is collected immediately after cord blood retrieval. It is important to use advanced methods to isolate and expand MSCs before cryopreservation.
Key factors for effective storage include:
-
Freshness matters: Fresh cord tissue ensures higher MSC viability, and the processing method plays a critical role in cell usability [9].
-
Bacterial testing: Essential to maintain the long-term viability of cells.
-
Cryoprotectant solutions: These specialized solutions shield cells during freezing to prevent damage.
Americord's proprietary CryoMaxx™ processing for cord tissue yields a higher number of viable cells. Clinical trials are currently investigating MSCs for conditions such as multiple sclerosis, autism, and sepsis, showing encouraging early outcomes [4]. These developments highlight the expanding role of cord tissue in regenerative medicine.
Comparing Cord Blood and Cord Tissue
HSCs vs MSCs: Main Differences
Cord blood and cord tissue differ in the types of stem cells they contain and their uses in medical treatments. These differences influence their therapeutic roles and how they are stored.
| Characteristic | Cord Blood | Cord Tissue |
|---|---|---|
| Primary Stem Cell Type | Hematopoietic Stem Cells (HSCs) | Mesenchymal Stem Cells (MSCs) |
| Cell Development | Transform into blood and immune cells | Differentiate into bone, cartilage, muscle, and nerve cells |
| Current Applications | Used to treat blood disorders, immune deficiencies, and certain cancers | Investigated for regenerative medicine and tissue repair |
| Treatment Status | Treats over 80 blood-related conditions [11] | Involved in over 300 clinical trials [11] |
| Collection | Extracted from umbilical cord blood shortly after birth | Taken from Wharton's jelly in the umbilical cord |
These factors highlight their unique roles in both established treatments and experimental therapies.
Current Treatments and Research
Cord blood is already used in treating more than 80 blood-related diseases, including certain cancers and immune deficiencies. Meanwhile, MSCs from cord tissue are being studied in hundreds of clinical trials. These trials focus on regenerative medicine, such as tissue repair, addressing connective tissue disorders, and tackling autoimmune conditions. Together, these stem cell sources offer complementary benefits for medical advancements.
Storage Options and Costs
The cost and storage requirements for cord blood and cord tissue banking vary. Americord offers processing services with initial fees ranging from $1,500 to $3,000, and annual storage costs (in some cases) between $150 and $300 [13]. Many companies also provide bundled options for storing both cord blood and tissue, offering better overall value. These storage plans play an important role in deciding the right banking option for families. Also pricing is subject to change, for the most up-to-date prices visit americordblood.com/pricing.

Decision Criteria
When deciding on cord blood banking, it's important to review your family's medical history. Conditions like blood disorders, immune deficiencies, or cancers might make this option worth considering [14]. Americord offers various payment plans to fit different budgets.
Here are the main factors to keep in mind:
-
Family Health: Look at your family's history for illnesses treatable with HSCs (hematopoietic stem cells) or MSCs (mesenchymal stem cells).
-
Finances: Compare upfront processing costs and ongoing storage fees to find a plan that works for you.
-
Storage Duration: Decide whether you want annual, fixed-term, or lifetime storage.
-
Medical Developments: Think about how stem cell therapies are evolving and their potential future uses.
This approach is based on the distinct uses of HSCs and MSCs covered earlier.
