Placental Tissue with CryoMaxx™ ProcessingTM

Americord is the pioneer of and only cord blood bank to offer CryoMaxxTM Placental Processing – because stem cell banking should benefit the whole family.

We know your first priority is the well-being of your child, but with CryoMaxxTM Placental Processing, Americord is also committed to helping the rest of your family live healthier, longer lives. These stem cells can be used to treat your newborn, but also every other first- or- second-degree relative. That means mom, dad, siblings, and even grandma and grandpa can use these cells, should the need ever arise. Banking this tissue is an opportunity to give your entire family access to the future of regenerative stem cell medicine.

What is The Placenta?

The placenta is a disc-shaped organ that develops during pregnancy and is attached to the wall of the uterus. It connects to the baby via the umbilical cord. The umbilical cord delivers oxygen and nutrients to the baby and removes waste products from the baby. 

The placenta holds an important role during pregnancy. It acts as a barrier to bacteria and viruses to protect the baby. It also produces hormones and signaling molecules that help the baby grow.

Why is the Placental Tissue Important?

The placenta can do so much more than protect the baby in the womb! The placental membrane consists of two layers: amnion and chorion. The amnion layer is baby facing. The chorion layer is maternal facing. When both layers are cryo-preserved, potential treatment opportunities exponentially multiply for your baby, their siblings, parents, and even grandparents.

The Placental Membrane Contains:

As researchers have studied placental membranes in more depth, they have learned that each part of the placental membrane plays a significant role in regenerative medicine. The key elements of placental membranes include:⁵  

  • Amniotic Epithelial Cells (AECs): Present on the top-most layer of amnion and can differentiate into various types of cells and tissue types.⁶
  • Amniotic Mesenchymal Stem Cells (AMSCs): Multi-potent stem cells capable of differentiating into a number of different cell and tissue types.⁷
  • Chorion Trophoblast Stem Cells (CTSCs): Present in the lowermost layer of chorion and are precursor cells of differentiated cells of the placenta responsible for oxygen and nutrient exchange
  • Growth Factors: Signaling molecules that regulate cell growth and tissue regeneration.
  • Cytokines: Signaling molecules that regulate inflammation.
  • Extracellular Matrix (ECM): A three-dimensional structure consisting of various collagens and proteins that directs cellular behavior such as differentiation, proliferation, and signaling.

Clinical Trials Using Placental Tissue

The placental membrane has been used for more than a century to successfully treat wounds and burns.¹⁻³ The first known application was at Johns Hopkins Hospital in 1910. 

Amniotic epithelial cells and amniotic mesenchymal stem cells are currently being studied for:⁸⁻⁹

  • Autoimmune diseases
  • Cancer
  • Graft vs Host disease
  • Gynecological conditions
  • Lung diseases
  • Neurological disorders
  • Orthopedic conditions

Placenta tissue containing multi-potent cells, growth factors, cytokines, and ECM is being studied in a number of clinical trials. The amnion layer was specifically chose by scientists because it has a structure that is similar to that of skin and ocular surfaces:¹⁰⁻¹⁶

Amnion Membrane

  • Corneal Healing
  • Dry Eye

Amnion + Chorion Membranes

  • Chronic Venous Leg Ulcers
  • Diabetic Foot Ulcers
  • Knee Osteoarthritis
  • Pressure Ulcers

What Clinical Research is Being Conducted on Placental Tissues - Placental Tissue

The amnion has a structure similar to that of skin making it an ideal option as a skin substitute to treat wounds.¹⁰

The Difference Between Cord Tissue and Placental Tissue Banking

Many private cord blood banks cryopreserve cord tissue, but very few offer placental tissue banking. Americord is the only company to offer CryoMaxx™ Processing for cord tissue and placental tissue. Placental tissue contains more cell types compared to cord tissue.

Cord Tissue vs Placental Tissue 600x331 - Placental Tissue

Cord tissue and placental tissue have different application uses. Cord tissue is used for surgical applications inside the body (ex: tendon repair, cartilage repair, or orthopedic surgery). Placenta tissue used for topical applications (ex: wound healing, treating eye conditions, ulcers).

Americord CryoMaxx™ Placental Tissue Processing

Americord’s unique proprietary CryoMaxx™ processing method uses a minimal manipulation method to isolate the amnion and chorion layers of the placental tissue and retain their inherent multipotent cells, growth factors, and cytokines. 

The amnion and chorion are cryopreserved and stored in multiple vials, ensuring the potential for multiple uses for your baby, siblings, parents, or grandparents. This processing method creates a versatile tissue and gives families the flexibility to use:

  • Amniotic epithelial cells, amniotic mesenchymal stem cells, and chorion trophoblast stem cells for therapeutic applications.
  • Amniotic tissue (amnion + chorion) containing multi-potent cells, growth factors, and cytokines for wound and ocular applications.

Special Note to California Residents

CryoMaxx™ Placental Tissue Processing is currently not available for residents in the state of California. Placental Tissue 2.0™ is offered to California residents interested in placental tissue cryo-preservation. Americord’s unique proprietary Placental Tissue 2.0™ processing method uses a minimal manipulation method to isolate the amnion layer of the placental tissue to retain its inherent multipotent cells, growth factors, and cytokines. Read More.

Cord Blood + Placental Tissue

$5,998 OR $350 ANNUAL

Placental tissue banking is the process of collecting stem cells from the placenta after delivery and storing them for future medical or therapeutic use.
The placenta is a valuable source of two types of stem cells, mesenchymal stem cells (MSCs) and amniotic epithelial cells (AECs), that can already be used to treat wounds and certain eye conditions, and are also at the center of advanced clinical trials to establish new treatments for a wide range of conditions, including cerebral palsy, cancers, organ failure, and injuries to bones and joints.
Those wishing to bank placental tissue can obtain a collection kit from Americord. After delivery, the placenta is placed in the kit and collected by a medical courier, who takes it to the lab for processing and storage.
The stem cells in placental tissue can be safely used for all first- and- second-degree relatives, a revolutionary development in stem cell medicine. This fact, combined with the incredibly diverse set of treatment possibilities in the clinical trial phase, make placental tissue banking an important consideration for any family.
Placental tissue is currently approved to treat wounds, including surgical scars, and certain eye conditions, including some that can lead to blindness. The treatment potential being explored is even wider, as a number of cancers, organ conditions, and injuries to bones and joints are the subject of trials.
Like cord blood, placental tissue can be safely and effectively stored indefinitely in proper conditions. Americord’s most common storage plans are for 20 years. These plans can be extended at any time, and lifetime storage plans are also available.
Private placental tissue banking became widespread in 2011, the same year Americord began offering the service. Americord debuted Placental Tissue 2.0™ in 2019, the most advanced process that enables the broadest application of stem cells.
Americord has flexible payment options to make stem cell banking as affordable as possible for more families, including one-time, annual, and monthly payment plans. First-year costs can be as low as $1,549.
The stem cells in placental tissue can safely be used for all first- and- second-degree family members. That means that banking provides siblings, parents, and even grandparents with access to treatments and trials using these stem cells.
